 (new ticket created, as #8864 seemed to be the same issue, but wasn't in
 the end)

 Trunk have issues to playback MPEG4 files, at least (but perhaps not
 limited to) MPEG4 files created by mythtranscode.

 I've uploaded a 20MB sample here:
 https://docs.google.com/leaf?id=0B-_nZameGeN-
 NTY5NGVjOGYtMDYzNS00Zjc4LWI3OGYtOTk2MzU4MzczZmVj&hl=da&authkey=CJv8zvAO

 The sample plays with mythavtest on 0.23-fixes, but will fail 20-90% of
 the time on trunk r26520 (both VDPAU and Xv). The video playback will
 freeze on one of the first frames, while the audio will continue to play
 correctly. Doing a fast forward or rewinding causes the screen to turn
 grey. Just like 0.23-fixes, mplayer doesn't have any issues with the
 sample. I'm attaching "mythavtest -v playback" logs from trunk.

 All of my recordings are automatically transcoded by MythTV from MPEG2
 (Hauppauge HW encoder) into MPEG4 - the sample comes from one of these
 files.

Comment:

 paul, I don't see anything in your logs indicating that you have the same
 issue. I'm not saying that you don't have a similar issue, just that it's
 not the same issue handled by this ticket. I've extended the description
 to be more specific about the issue.

 Anyway, "me too" messages doesn't help the developers and are forbidden,
 please read the TicketHowTo at http://svn.mythtv.org/trac/wiki/TicketHowTo
