Comment(by Klavs Klavsen <kl@…>):

 I have the a problem, that seems to be the same problem (with recordings
 from DR Ramasjang an mpeg4 (I believe h264) dvb-t channel).

 When playing the internal mythplayer (from debian-multimedia experimental
 - 0.22-0.4 it says there's only 8 minutes recorded - but if I actually
 play it - it will play beyond the 8 minutes.
 Also there's no sound.

 If I play it in mplayer the video has sound and the entire recording is
 there - but it seems rather messed up.

 I'm suspecting a "recording error" of sorts? (unless the source was with
 errors?) - here's mplayer's output when playing:

 It stops here - until I try to fast forward.
 FAAD: error: Channel coupling not yet implemented, trying to resync!

 after a 10 second skip.

 then I try to fast forward some more.. and below pops up.

 The timer in the movie is also way off.. It appearently starts the timer
 at: 4:24:10 and says ending at 15:21:19.

 It seems to play fine in mplayer - except if I fast forward at all - it
 goes to 100% cpu usage, but this may be my system not being powerfull
 enough to also handle the buggy stream (The system plays 720p without any
 problems).

 If you need a sample (or the full 844MB) - I'll make it available for
 download immediately.
