Yep I can reproduce this myself now. After cutting out 9 segments in a
file I need and an A/V Offset in xine of -00:00:44 (39600 pts) to get
the audio back in sync after the last cut. After each cut the sync
gradually gets further out of sync.
I'll contact Geoffrey Hausheer who did the mythtranscode --mpeg2 stuff
to see if he has any ideas on how to fix this.
