I am facing a problem with audio sysnc, when i played AVI files.
While playing the video file may be after 20 minutes; automatically the sound starts from the begining and the video continues to play un-interupted.
From the properties of the file i found there are 4 dropped frames.
(May be when the auido reaches one of the dropped frame it starts from the begining).
Then i had to use my PC with VLC media player to see the movie without any problem.
