[mythtv-users] Video player works for first 95% of movies, last 5% have fast/jerky audio/video?

[Jay Summet]

I have used Myth to rip a large number of my DVD's to AVI files (using
either the Excellent or Good setting).  Now that I am starting to play
back the movies, I have found something that is very troubling.

On many of the movies, the first 95% of the movie (e.g. 1:13 min of a
1:26 movie) plays flawlessly. However, near the end of the movie, the
audio and video starts to speed up and get jerky. (Audio/video sync is
also thrown off.)

I have copied the files to a different box and played them with totem
and mplayer and was happy to find that the files appear to be just fine.
(or maybe mplayer/totem deal with them better?)

It seems that the problem is with the mythv internal video player.

After a random sample of movies, I'd say that at least 50-70% (but not
all!) of the movies have this problem. The problem survives reboots of
the mythtv box.

I am using Xvmc for HDTV playback (with no problems), (OSD is B&W) but
not for the internal video player. (OSD is in full color)

Even if I ESC from the movie and then go back into it (the internal
player resumes at the same spot) the problems continue as before. If I
rewind the movie, it works correctly before the "problem starting spot"
but when it hits that spot, the problems resume.

I suspect it may be a problem that is caused by the MythTV ripping
system, as I have re-encoded movies using mencoder that then play back
correctly in the internal video player.

Has anybody else experienced this?  Any ideas what is causing it? And
how to fix it?

Thanks,	
Jay
