I updated my system, and now mythtv will not jump ahead or backwards properly. The same recording plays fine in XINE, and I can jump ahead without freezing in XINE. The current time display goes to the end time when I jump ahead in mythtv, but the actual position in the recording does to the beginning the first time. If I try to go backwards, it jumps out of the recording and goes back to the menu. I have: media-tv/mythtv-0.21_p19961-r1 Here is some output while trying to jump ahead: 400 New DB connection, total: 3 2009-03-24 00:36:27.401 Using realtime priority. 2009-03-24 00:36:27.401 Connected to database 'mythconverg' at host: localhost 2009-03-24 00:36:27.509 OpenGLVideoSync() 2009-03-24 00:36:27.537 Video timing method: SGI OpenGL 2009-03-24 00:36:35.119 [mpeg2video @ 0x7f30e2f9dcf0]current_picture not initialized 2009-03-24 00:36:35.119 AFD Error: Unknown decoding error 2009-03-24 00:36:35.120 [mpeg2video @ 0x7f30e2f9dcf0]warning: first frame is no keyframe 2009-03-24 00:36:42.506 [mpeg2video @ 0x7f30e2f9dcf0]releasing zombie picture 2009-03-24 00:36:50.077 TV: Attempting to change from WatchingPreRecorded to None 2009-03-24 00:36:50.122 ~OpenGLVideoSync() -- begin 2009-03-24 00:36:50.122 ~OpenGLVideoSync() -- middle 2009-03-24 00:36:50.123 ~OpenGLVideoSync() -- end 2009-03-24 00:36:50.687 TV: Changing from WatchingPreRecorded to None 2009-03-24 00:36:50.870 DPMS Reactivated. 2009-03-24 00:36:51.996 AFD: Opened codec 0x9ff200, id(MPEG2VIDEO) type(Video) 2009-03-24 00:36:51.996 AFD: codec AC3 has 6 channels 2009-03-24 00:36:51.997 AFD: Opened codec 0x158d910, id(AC3) type Here are ffmpeg levels: [I--] [ ] media-plugins/gst-plugins-ffmpeg-0.10.5 (0.10) [I--] [ ~] media-video/ffmpeg-0.4.9_p20090201-r1 (0) Reproducible: Always Steps to Reproduce: 1.Record ATSC-MPEG/AC3 TV 2.Try to jump ahead while playing back a recording 3.

The problem appears to be ffmpeg. This ffmpeg worked for me: media-video/ffmpeg-0.4.9_p20090201 This ffmpeg does not: media-video/ffmpeg-0.5-r1
Please test with a newer MythTV version. There have been updates in this code path.
I can play MPEG2 just fine now. I still can't skip ahead in an Xvid-MPEG4 ogm file (but it will play as long as I don't try to skip). xine can skip just fine with the following file that fails in mythtv (mythfrontend): $ mplayer -vo null -ao null -frames 0 -identify soldworld.ogm MPlayer SVN-r29463-4.3.4 (C) 2000-2009 MPlayer Team mplayer: could not open config files /root/.lircrc and /etc/lirc/lircrc mplayer: No such file or directory Failed to read LIRC config file ~/.lircrc.
