The official announcement for 0.19 is here. It has all the download links and information about the official release.

This is a summary of changes from 0.18 to 0.19 generated from fixed tickets in the bug tracking system. The 0.19 release tagging was SVN changeset 8925.

The major changes in this release are:

  • LiveTV rewritten to support saving buffered content while watching
  • Signal Monitoring for DVB and pcHDTV recorders
  • Ending times may be changed while recordings are in progress
  • Playgroups allow for default playback options on recordings. See important note below
  • Channel changes can be made across tuners without changing tuners manually first
  • New popup keyboard simplifies setup using remote
  • Preview schedule changes when making adjustments to recording schedules
  • Added ability to control MythFrontend through a telnet socket
  • Closed captioning support on PVR-250/350 (but not 150/500) cards, DVB subtitles, and other cards supporting VBI information.
  • New theme (MythCenter), new plugin (MythFlix), and new contributed programs (mythlcdserver, mythwelcome)
  • Signficantly overhauled MythWeb, please read the README for details and installation instructions
  • Added a basic internal DVD player, removing the need to use Xine or Mplayer
  • mythfilldatabase (and specifically the North American listings grabber which retrieves data from DataDirect) has been modified to respect Zap2It Labs' 'recommended download hour' suggestion to reduce the load on Z2L's servers

Read on below for all the details.

It is highly recommended if you are using the Nvidia binary VGA drivers that you use version 7676 or earlier as later revisions have serious problems with features like XvMC and OpenGL sync which can result in poor performance or lockups. (If you're running a version older than 7676 which provides all the features you need, you need not upgrade.)


New Features

  • Major LiveTV changes - LiveTV is now treated more like a normal recording in that you can press "R" while watching LiveTV and everything you've seen since you switched to that channel will become a stored, named, recorded program. LiveTV recordings are placed into a separate LiveTV recording group and hidden from view by default. You can enable viewing of these recordings if you desire. LiveTV recordings are expired before any other content.
  • Auto-expire is forced on for all systems because of the LiveTV changes. This would be a good time to confirm your expiration settings are appropriate for your system. If you use your partition for other content, leave yourself a buffer large enough to handle your needs. Adjust the auto-expiration timer to ensure that programs are expired as needed to free space. Check your recording schedules and existing programs to be sure their auto-expiration setting is correct.
  • Recording ending times may be changed while recordings are in progress
  • Recordings in progress on a slave backend will be discovered if the master restarts and the master can restart a recording on another card if a slave fails during a recording
  • Added playgroups which allow default playback options (timestretch, skip and jump intervals) to be set on a per recording schedule basis.
    Important: The new default playback group does not inherit the skip settings previously configured in mythfrontend. Please visit the Playback group configuration screen to reset your defaults to the expected behavior.
  • Added support for changing channels across tuners during LiveTV without having to change tuners manually first.
  • The Program Details page is now scrollable and includes more details from the listings and more MythTV specific information about the show
  • Added popup keyboard in text boxes
  • Schedule changes can be previewed when modifying recording schedules to see the results of changes before saving them
  • Added ability to control MythTV by telnetting to a TCP port on the front end and typing text commands. See Ticket 1092 for details.
  • Filename changes. Recordings are now saved without their ending times as part of the filename and MPEG-2 recordings will have an .mpg extension instead of .nuv like MPEG-4 or RTJPEG recordings.
  • Sending SIGHUP to the backend will rotate log files
  • Added support for importing channels.conf for DVB and ATSC cards
  • Added option to select audio track or subtitle track from OSD during playback
  • Added support for DTS pass-through audio
