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

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?
