[MPlayer-users] a-v help

[radus]

Hello!
I have a question, i want to know if smth is possible

I have an avi which works great for the first 20 or so minutes, after which
there is a portion of 20 seconds in the sound that repeats itself.
After correcting with +/- buttons it syncs but then the sound constantly goes 
ahead and i can't correct it anymore
The question is why after the +/- correction why does the sound go ahead, is 
there smth in the sound part of the movie or is it smth mplayer trigger i 
must disable ?
