That is typically when video decoding takes a lot of time. When all or
more time between two video frames are needed to video/audio decode and
output, mplayer starts having problem with a-v sync.

It may well be that this added code to correct faulty pts values, does
not work well when mplayer cannot get a frame ready to be displayed at
correct time.
