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". Note: This setting has moved/changed name in v .21
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.

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.
Live TV is treated as a recording and it is saved in your media list. The live TV recording will 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 time-stretch playback was introduced, which covers both stretching and compressing time. Specifically, 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. You can also use this feature to play the TV Stream in slow motion, nice for instant reviews of sports events or following a difficult foreign language movie.
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.
Press the key, and the OSD will show the position in the recording.
If you try watching live TV and all the Tuner cards are busy recording, you will get the following screen.
