Using A Myth Box From Day To Day
Ah, yes; the part you've all been waiting for. :-)
This section identifies all the things you can do with a MythTV unit, and explains how they work and how to control them. Hopefully, it will also identify things which can be done more than one way, and point out the most effective choice (and why you might want to do it another way anyway).
MythTV is, as we've said, a very capable, powerful, and most of all expandable system. The practical effect of this is that as we go along, we will describe things which can only be done with more than the basic configuration, or which work differently if you have more than the basic configuration.

Conventions and notes
Whether your screen will look exactly like the screenshots in this manual will vary depending on the theme you have chosen.
- If you want to do screenshots of live TV you must turn off XV video acceleration; you can use the following command to run Mythfrontend.
$ NO_XV=1 mythfrontend
- This does software rendering of the video stream, so it is slow. To slightly improve speed, make sure you don't have any deinterlacing turned on.
- Editor's note: The images below are using only one of the several available OSDs. Personally, I prefer some of the other, "prettier", OSDs (no offense to the author of that OSD). Also note that some of the behaviors noted in this document will change with the release of 0.19 (mainly the LiveTV section). --TylerDrake
- Editor's note: Please keep configuration related items as well as deep technical explanations to a minimum in editing this section. This section of the manual is for end-users; technical topics should be covered in the setup and config sections --Mikec 06:06, 28 January 2006 (UTC)
Remote Control Buttons
The remote button icons represent common names for remote control keys. In reality, how these map to physical keyboard keys will depend on how your particular machine was configured. You will need to setup your Remote Control to suit.
You can find a full list of keyboard keys and functions on the keybindings page.
MythTV has been designed to be used via the "10ft Interface": you should be able to drive its day to day functions from 10ft away sitting comfortably on your sofa.
In many respects, this is a compromise between functionality and simplicity. This is especially the case given that the average Remote Control only has about 40 to 50 keys (10 of which are numbers). Compare this with MythTV's over 100 keyboard functions.
MythTV users will also cite the much needed WAF or GAF; that is, Wife/Girlfriend Acceptance Factor. The good news is the 80/20 rule applies - you can do 80% of your day to day things with MythTV on about 20 keys on your remote.
Live TV vs MythTV
MythTV introduces a whole new paradigm shift in the way you watch TV. Traditional TV forced you to watch against the broadcaster's schedule. This meant that you scheduled your time around your favorite programs. This also created the channel-surfing culture, cycling through channels just to see what was on, more often than not there was never anything you liked.
MythTV introduces the Electronic Program Guide, or EPG, with its full description of what is currently being broadcast and what will be broadcast in the coming weeks. The guide is stored in a relational database so that you can make queries such as find episodes of "Desperate Housewives".
MythTV watching is more like the way you would watch your DVD collection. You browse what is in your collection and watch what you want, when you want. However instead of going out and buying DVD's, you harvest your favourite programs as they are broadcast, record them to your hard drive and watch them as you want.
MythTV has plugins that actually allow you to just look for broadcasts of your favourite films and, as soon as they are broadcast, record them to your hard drive to add to your collection! You can even have the system make recommendations and record them against the kind of shows that you like.
Many long-term MythTV users will say that they have stopped watching live TV and are instead spending time each week scheduling the system to record the kind of shows they like and just browsing through their collection of shows and movies and watching what they like at their leisure.
Dealing with Commercials
Whether you like to watch adverts/commercials is a matter of taste. MythTV on the otherhand gives you a choice of skipping over these in your recordings. As such MythTV is often compared to a TiVO. There is much activity in the industry with respect to commercial handling, and forcing users to watch these ie. you cant fastforward or skip these with Personal Video recorder devices or applications, indeed it may even become illegal to do so.
Over the years MythTV has transformed itself into a full blown media hub, able to handle all digital media including photos, music, videos, DVD and CD plus much more. More importanly since the 0.20 release, MythTV is now able to support the new Universal Plug and Play (UPnP) media server/client and control point standard, so that it can interact with all manner of other media applications and devices.
MythTV consists of two main applications: MythBackend and Mythfrontend. Mythbackend handles all aspects of your TV cards and capturing live TV shows into recordings, and most importantly all the information about these recordings and any media you have such as music and photos. You will always need to start the Mythbackend first. Mythfrontend handles the user interface and the interaction between you, your remote control and the mythbackend server.
Ideally mythbackend/mythfrontend should be autostarted when you power on your machine, see the user Manual:Detailed configuration Backend and user Manual:Detailed configuration Frontend on how to do this. Many users just leave their machines running all the time so that they can be sure to capture scheduled TV shows to recordings. For those of you that are concerned about electricity usage, then you can have your MythTV machine automatically wakeup just before a show starts, and then shutdown after the show has been recorded. The mythbackend server will automatically shut down when it is idle, ie is not connected to a front end, or is not recording.
You can also start Mythbackend from a terminal session with the following command.
You can also start the MythTV Frontend user interface from a terminal session with the following command.
mythfrontend can be run either in full screen mode or inside a window.
Once MythTV has started you will be presented with the MythTV Front page. Here is one using the Retro Theme.
You can see a collection of Themes available here MythTv Themes.
MythTV Welcome Screen
0.19 introduced the concept of a "welcome screen" so that the frontend could be started with a press of the remote control. This has been introduced for those people that want to use scheduled wakeup and shutdown to record scheduled shows to save on power consumption. Prior to this the Frontend would always start up which in turn meant that the backend would never shutdown when the recording had finished, thus defeating the whole purpose.
The welcome screen will show the status of the backend and wait for you to manually start the frontend with your remote
You should set your system to autostart with mythwelcome rather than mythfrontend. Mythwelcome will automatically start mythfrontend in the event that the system is normally powered on. You can change this behaviour by accessing the configuration page. Press
You may find it helpful to read the Mythwelcome configuration page
Watching Live TV
When you select Watch TV from the front page, MythTV will automatically go to the default channel when you setup the mythbackend. You can also have it go directly to to programme guide.
While watching Live TV you can change channels with . There is a pause of several seconds while MythTV buffers the new channel. People often find this pause disconcerting as they are typically coming from a normal TV where they are used to "Channel Surfing", though it's fairly common on digital cable TV service, as well. The way to overcome this is to put MythTV into Browse Mode, and this will become the default as of 0.19 for precisely this reason.
Browse Mode is enabled under
- TV Settings->Playback->On Screen Display,
check the box "Always use browse mode when changing channels in LiveTV".
Press to browse the program information on the next/previous program with the OSD. Then when you see the program you want, press and MythTV will jump to that channel. While in Browse mode you can also use to see what shows are coming up next, by scrolling the program guide earlier and later in time.
You can also jump directly to a channel by pressing the number keys. Press 1 and it will jump to the first channel in your channel list, press 12 it will jump to the twelfth channel in your channel list etc. You can organise your channel list with the MythTV-Setup program.
- The OSD will show the volume provided you have set MythTV to use its internal volume controls. It is possible to set MythTV to bypass its internal volume controls and send the audio directly to your soundcards SPDIF output. In this case you should program your remote's volume up and volume down keys to control the volume on your AV amplifier.
Changing Aspect Ratio
You can step through the different screen aspect ratios with the key.
|4:3||Classic TV Aspect Ratio|
|16:9||True Anamorphic Widescreen|
|4:3 Zoom||Crop top and bottom to fill Wide Screen TV|
|16:9 Zoom||Crop sides to fill 4:3 TV|
|16:9 Stretch||Resize 4:3 picture to fit a Wide Screen TV|
Live TV Capabilities
MythTV offers some of the most sought after features of modern Media Centres.
Pause Live TV
Pausing live TV is great when the phone rings during a show or your little ones need a comfort break during a movie.
By pressing on your remote the picture will freeze, and MythTV will start to buffer Live TV to the hard drive. The OSD will appear showing seconds behind realtime TV and (in version .18) how much live TV has been buffered as a percentage of total buffer space.
In .18, if you changed channels or exit from watching Live TV then any buffered TV will be lost. 0.19 changes this by treating live TV as a recording and saving it in your media list. The live tv recording is set to auto expire when the hard drive nears being full.
While the picture stream is paused:
Chase TV Playback
With Chase TV Playback the system can be recording live tv while you are watching the same program behind realtime. It is somtimes referred to as Timeshifting TV.
If you are coming to MythTV from using a Video Recorder, you might want to enable the "sticky" keys option. This keeps the fast forward or rewind on even after you release the key. Subsequent presses of or will increase the speed of the rewind or playback. When you reach the point you want to watch, press to resume normal playback.
Time Stretch Playback
At the 0.17 release of MythTV the concept of Timestretch playback was introduced. Though, it's really 'time-compression'. This allows the user to adjust the playback speed slightly, but keeps the audio at the same pitch. If you're recording a lot of shows, timestretch lets you get through them faster. So now you can watch a 1 hour show in 40 mins without feeling like you are listening to Alvin and the Chipmunks.
During Live TV you can use this feature to play the TV Stream in slow motion, nice for instant reviews of sports events.
Electronic Program Guide (EPG)
The Electronic Program Guide will allow you to get more detailed information on what is being broadcast currently as well as scheduled programs that are coming up.
- TV settings->Playback Settings->OSD
Select the Program Guide and the Full EPG will show.
The EPG also allows direct channel jumping by entering a channel number. By default, it is off. You can turn it on in the
- TV -> Guide Settings.
When you press a number key MythTV gives you 2.5 seconds to enter additional digits, (These are displayed on screen as you press), after which it will jump to the closest channel it can find that matches the digits you have pressed.
Concurrent Channel Watching
If you have multiple tuner cards you can watch two channels at once using the Picture in Picture (PIP) facility. You can record one programme while you are watching another. Turn on the PIP via the Onscreen Menu by pressing the key while watching Live TV.
Recording Live TV
While watching Live TV press the key, MythTV will start recording the show from the point that you started watching it until the show is finished, according to the Guide schedule. This might cause some rescheduling of later recordings.
The Tuner card being used to record from will be locked until the recording has finished or you explicitly cancel the recording. If you have multiple Tuner cards you can now change channels with the keys. MythTV will continue recording the current show and switch to the next available Tuner card. If there are no more available Tuner cards then the keys will just jump back and forth in the recording.
The Recording capability of MythTV is its most powerful feature and sets it apart from just about anything else on the market. It allows you to have complete control of even very complex recording scenarios. There are three ways to find the shows that you want to record.
1. Use the EPG.
This is good for recordings coming up in the next 24 hours, can be difficult if you want to schedule lots of shows, or don't know where and when they are being transmitted.
2. Use the Programme Finder
You can find this under Manage Recordings->Schedule Recordings->Programme Finder
This is good for scheduling lots of shows as well as when you want to schedule something that is more than a day away, saves lots of scrolling and searching the EPG.
3. Custom Recordings
For those of you that want to do really advanced stuff you might find it helpful to read the section on Custom Recording
If you have multiple tuner cards, MythTV will try and resolve schedule conflicts by searching for repeat broadcasts of the same show as well as trying to handle non broadcasts due to changes in schedules. For recording of multiple episodes of a show, MythTV will look at the episode information to identify unique episodes.
You can change Recording priorities in Setup->TV Settings->Recording Priorities
Common recording scenarios

How MythTV Records
Ringbuffer and Recordings
Prior to the 0.19 release MythTV treated timeshifting ie chase play and recording a programme differently. There was a Ringbuffer that handled the timeshifting element, whereas Recordings were saved into their own file. This had some negative side effects.
1. If you were watching a live show and 15 minutes into it you decided that you wanted to record it, pressing the record key only recorded the show at that point. You lost 15 mins worth even though those 15mins were in the ringbuffer.
2. Changing channels was unnecessarily slow because the system had to mess around with the ringbuffer each time.
With 0.19 Timeshifting and recording are one and the same. Now if you press the record button 10 mins into the show, all MythTV does is make a change in the database to indicate that this is a Recording and by magic it appears in your recordings collection.
Live TV recordings that have not been transitioned appear in the Default Recordings group.
Expirations of Recordings
If your machines starts to run low in disc space it will start to expire (delete) recordings to make room. The default behaviour is to delete oldest shows first, and is checked every 10 mins. You can mark Recordings as permanent in the Recording Browser. Select the recording you want and press and select "Dont Auto Expire".
You can change the default beviour in TV settings->General settings-> Global Auto Expire Settings
MythTV recordings are automatically flagged for commercials, ie there are markers put in the database that tell the system where it believes commercials start and end. This allows you to jump over commercials when playing back recordings. You can also use this information to delete the commercials when you export the recordings.
You can change the default behaviour in TV settings->General settings->Job Queue
You might find it useful to have a look at Commercial Flagging which explains how it works.
MythTV by default holds all its recordings the /mnt/store directory
You can browse these recordings in Main Screen-> Media Library-> Watch Recordings from Mythfrontend.
MythTV will show a preview of your recordings if this has been enabled under TV Settings->Playback->View Recordings.
Play Recording Groups
You can play a collection of recordings for example all episodes of a particular series.
The recordings are organised into Recording Groups on the left of the screen. The Group "All Programmes" contains all recordings. Use the keys to select the recording group. Press the key to play that group of recordings
Play Individual Recordings
Indivdual recordings from each recording group are on the right of the screen. Use the keys to move between the Recording Groups and recordings. Once you are in the recordings pane, use the keys to move between recordings. Press the key to play that recording.
MythTV allows you to create Playlists of Recordings. You can select complete Recording Groups to add to the Playlist, or individual Recordings. This is useful if you need to keep the kids entertained for more than a few hours.
Adding Recording Groups to the Playlist
Adding Individual recordings to the Playlist
Playing recordings in the Playlist
You can see what Recordings are in the recording Playlist by selecting the "All Programmes" group. Selected Recordings are highlighted in yellow.
Note: Once you exit the watch recordings page. Your Playlist will be lost.
The MythTV master backend is responsible for managing the schedule for all TV tuner cards on the master and any slave. Its job is to search the TV listing for the shows you have requested and assign recordings to the TV tuner cards. If none of the shows that you've chosen overlap, it simply records all of the shows. However, if there are shows where the beginning and end times overlap, the scheduler follows rules that you've specified or makes logical decisions about what would be best if you haven't expressed any preference.
If you have a lot of recordings scheduled, you can check to see what they are, as well as resolve any conflicts that the system can't handle, with the upcoming recordings browser. Main Screen->Manage Recordings>Upcoming Recordings.
There are two 'views' available.
This tells you if there are any conflicts that would prevent one or more shows from being recorded.
The items in the list are colored in the record color for things that will record, white for things that may need attention, gray for those that do not need to record and yellow when there is a time conflict. Items at the top of the list may also be highlighted in red indicating that the recording is in progress.
Tuner Number and Status Code
Numbers indicate which card number has been assigned to record the show. Letters are used to indicate the reason that something will not be recorded. You can see what the letter means in the "Record Mode" Below.
This is a short status message for the highlighted item that indicates the type of record rule that was matched, the "total priority" for this showing and a one or two word explanation of the status code.
The Editor allows you to remove any commercials that the may not have been detected by the system during recording. You might also want to remove the lead in prior to a show or the overrun at the end of a show. The process of editing is often referred to as creating a Cut List. This is because MythTV does not actually cut the Recording. Instead it creates a collection of in and out points in the database that is associated with that recording.
The Timeline Editor will now appear
Use to change the amount to move. This varies between 0.5 Secs to 10Mins. You also have the option of 1 frame at a time, 1 keyframe at a time and finally a cutpoint at a time (jumps from cutpoint to cutpoint).
Use to choose between Delete before this point or after this point. Just add the cutpoints that you need. The system will remember these the next time that you bring the recording up. Red areas along the Timeline will be deleted (Skipped). Green areas will be played.
If you now transcode this recording the system will take the Cutlist and produce an edited Recording ready to be exported.
The transcoder re-encodes files from one MythTV format to another. There are two reasons to transcode
1. Allow users to create MPEG-4 streams to save space.
2. Physically cut the commercials or video segments from the recordings
Note this is not used for creating MPEGs for burning to DVD as you will get audio video sync issues, especially with DVB recordings. You need to use MythArchive for this or manually with Project X and DVD Author.
Use the Recordings Profiles to change how the system transcodes your recordings
mythfrontend->setup->recording Profiles->Transcoding recording profile.
now select either RTjpeg or MPEG-4 (selecting any of the hardware encoders will result in the transcoder not working). set the other parameters as you'd like. For best performance, you should match the audio to the 'Default' profile. If you plan to only use the manual transcoder, you can choose to set the video to be the same as the default profile too (as long as it is MPEG-4 or RTjpeg)
The transcoder can be used in two ways:
1.Automatically re-encode every file once it has completed recording
2. After marking commercials, the transcoder can be run manually to delete the commercials from the file (thus further saving space)
The two methods are independent. The first is an automatic process that can be enabled/disabled through the setup program; the second is a manual method which must be invoked on each recording individually.
You can transcode a recording that has already been transcoded, for example to cut a further section with no loss in quality provided you are going from and to the same format.
To enable automatic transcoding, do the following: start the setup program under the host-specific settings: set the Transcoder Auto-run checkbox, or in newer versions of the program, you may select automatic transcoding from any of the recording profiles you have set up.
Everything should now be setup properly. If you elected to use the Auto-Run feature, the transcoder will automatically launch after each recording is complete. The transcoder thread runs at a low priority, so it should not impact any critical tasks or other recordings.
If you want to manually transcode a program, simply press while watching a recording and select Transcode (you should have already finished marking all commercials and creating your Cut List with the Recording editor).
Once the transcode is complete, mythbackend will replace the old file with the new as soon as it is no longer in use.
MythTV 0.20 plugins now includes MythArchive for archiving your recordings.
What follows is for users of MythTV 0.19 or earlier.
At some point you will want to archive your TV recordings for safe keeping. There are however some complications with this, due to the way Digital TV content is held on your hardrive. MythTV stores its recordings in the "/mnt/video" directory by default. You will find files in here with a .nuv file extension and a long complicated name based on the recording schedule. These files are in NuppelVideo format.They are effectively MPEG-2 files with special markings to help digital TV cope with any dropped information during broadcast. To archive these files to DVD they will need to be converted into normal MPEG-2 files that are compliant with the DVD standard.
The process to archive these to DVD involves the use of several external tools as MythTV does not yet have a DVD burning option. The steps are as follows:
- 1 Split the DVB (NuppelVideo) file into separate Video and Audio files using [ProjectX]
- 2 Create a DVD MPEG-2 file using mplex (mjpeg tools)
- 3 Create a DVD Disc ISO image using DVD Author
- 4 Burn the DVD using K3B
For SUSE users a detailed guide is here []
Split DVB File with ProjectX
Project X takes a collection of DVB stream files and concatenates them into one big project. You can trim the files here also. It will then create synchronisation marks between the audio and video. You can use the default settings.
Create DVD MPEG-2 stream
We now can convert the above output video(m2v) and audio stream (mp2) generated by projectX to a DVD compatible stream. We use the mplex command, which is part of mjpegtools. You will then have a .mpg file with combined audio and video all nicely synchronised.
>mplex -f 8 -o 1.mpg 1.m2v 1.mp2
Create a DVD Image with KDE DVDAuthor
KDE DVD Author [KDE_DVDAuthor]will allow you to create very nice DVD's complete with animated menus. You do not need to compile it. Just download and click on the installer.kmdr icon and KDE will install it. KDE DVDAuthor is a KDE Kommander application.
KDE DVD\Author requires the following packages DVD Author, ffmpeg, lsdvd, normalize
Just follow the steps in the wizard, adding in the video , audio and images files that it asks for. It wil then generate a DVD ISO image once it completes.
Burn DVD image using K3B
K3B includes a wizard to burn DVD ISO images. You will find it under the Tools pull down. Tools-> Burn DVD ISO image. Just load up the ISO image from step 3. and you are done.
MythTV recordings can be exported into multiple different formats such as iPod or PSP compatible MPEG4 files, DivX and Xvid files, or files to burn to VCD, SVCD or DVD with the use of an external program such as nuvexport, which can be downloaded from https://svn.forevermore.net/nuvexport/.
Nuvexport is a command line program that can be used to create a copy of your recording in the following formats: XviD, SVCD, VCD, DVCD, DVD, DivX, ASF, MP3, PSP, iPod, and MPEG2 (though the iPod and PSP export options are currently unavailable). It does not alter the original file in any way, just gives you a new one in a folder of your choosing.
When run, it will use information from the MythTV database to give you a list of all your recordings to choose from, and allow various options such as resizing the video, cutting out sections marked with MythTV's edit cut list, altering the bitrate, and various other things. A work in progress manual for nuvexport can be found at http://www.inaudible.co.uk/nuvexport.
There is also a specialized script that allows you to transcode your files and subscribe to them on your iPod available at http://myth2ipod.com/. This utility uses nuvexport, and then does special post-processing with MP4Box to create an iPod-ready video. It will even generate an RSS feed for your shows, which you can subscribe to in iTunes. Currently (6/22/06) transcoding HD shows doesn't appear to work - you get rolling colors and disjointed sound. This is apparently a bug in nuvexport. SD shows work fine though.
Exporting to Flash
You may find it useful to read the section on exporting to your recordings to flash file format. This will allow you to easily watch recordings using a web browser.
As of 0.20 there are two ways to play DVD Discs on your Myth Box
- 1. Use the internal DVD player. It has complete menu and subtitle support. It will also bypass all of the clag such as anti-pirate and FBI warnings and go straight to the main movie.
- 2. Use an external player such as Xine or Mplayer. Xine offers DVD Menu support, but you will need to do some work to map your keys on your remote control so that they match those for MythTV to make sure that there is no confusion what keys do what. As this is an external player you also need to make sure that the audio options are set up within xine and MPlayer as needed. You may find it useful to read the Configuring Xine page
You might find it useful to have a look at the Ripping Guide to set up your system.
The MythTV DVD Plugin offers the capability to Rip your DVD's to the hard drive and then compress the movie from its normal 5-9GB file size to 700MB-2GB depending on the final quality that you want. When transcoding the system will use the settings defined in the frontend configuration. The default is to use XVID CODEC.
Select the Import option on the Myth Frontpage->Optical Disks->Import DVD
Press the "Space" key to select the options on each line.
|Select||Select this Video file for transcoding. A DVD will typically include multiple video files, eg trailers, directors commentary etc.|
|Name||The title of the DVD RIP|
|Quality||Options available are dependant on the DVD inserted
|Audio Track||Select which of the Audio tracks available on the DVD you want encoded with the video|
|AC3 Audio||Encode the AC3 Dolby digital surround audio track|
|Subtitles||Encode the Subtitiles with the video|
|View||Preview the Movie during Transcode|
Import takes several steps
- Copy the VOB video and Auido files to a temporary file (apprx 30Min). For "Pefect" it stops here.
- First Pass Transcode of the Video and audio files (approx 1hour per hour of movie)
- second Pass Transcode to reduce the file size even further (approx 1 hour per hour of movie )
If you have specified the quality to be "good", it will call transcode to do the .vob -> .avi with xvid or divx.
The transcode time will depend on the speed of your processor (numbers given using AMD XP2800)
Once Transcode has finished you should find the new compressed movie in your Videos directory, which is visible via the Myth Video manger.
Main Screen->Utilities /Setup -> Video Manager
The Default location for MythTV to hold all your Videos is at /share/Movies/DVD
The Defult location for MythTV to hold all your DVD cover art (Movie Posters) is at ~/.mythtv/MythVideo
Once you have either ripped DVDs or copied video files to the Video directory you will want to add both movie information as well as DVD cover art. You can do this via the Video Manager.
Main Screen->Utilities /Setup -> Video Manager
Press "i" and Myth TV will allow you to go the the Internet Movie database and retrieve information on your movie as well as matching Album Cover art. It does this by matching the name of the Movie. If it does not find an exact match it will offer you a list of options. In the event that it is not able to find any match at all, then you can enter the information manually to bring up the OSM. Select "Search IMDB".
Myth TV will now go the the Internet Movie database and retrieve information on your movie as well as matching Album Cover art. It does this by matching the name of the Movie. If does not find an exact match it will offer you a list of options. In the Event that it is not able to find any match at all, then you can enter the information manually.
Once it has finished it will return back to the browser and show you all of the detailed information
You may find it helpful to read the MythVideo page
you can browse your video collection using
Myth Mainpage->Media Library->Watch Videos

MythTV Gallery Module allows you to view all your photos as well as short movies from your digital camera. Myth Gallery will show your photos as they are organised in your file system. Myth will generate thumbnails of both folders as well as individual photos.
Many new digital cameras can now take high quality movies typically in MPEG 4 format as well as photos. Mythgallery can show these as well, provided that you have the video player setting set up to play that media type. Make sure that you do not have spaces in your directory names or picture names ie "2005 Winter Olympics" should be "2005_Winter_Olympics" or Mythgallery video player will not be able to find the file (this has been fixed in 0.19)
Select the Settings Option to bring you the Myth Gallery Settings screen

The query command currently only supports one subcommand which is used to query the current 'location' within Myth. The 'query location' command returns things like the following:
etc. for screens
and things like this:
Playback LiveTV 35:03 of 35:21 1x 31
Playback Recorded 0:00:23 of 1:02:21 1x 1031 2005-10-17T22:00:00
when playing a recording or LiveTV.
So, with the current implemention, you can telnet to a port, instruct mythfrontend to change to the Watch Recordings screen (jump playbackbox),and start playing a recording (play program 1031 2005-10-17T22:00:00).
Then during playback, you can pause, change speeds, seek around, and stop playback. You can query the current screen and jump to other locations including the main menu.
I think it might be nice to extend this functionality in the future to allow things like querying the list of recorded programs, deleting recordings, and other commands that would make managing a myth system remotely easier. It also might be possible to allow simple 'http' commands to allow controlling this via a web browser. A 'query recordings html' version of a 'query recordings' command could return html code to draw a page with links something like
