I have a DVD movie here in XviD format with PCM audio. When I try and convert it to DVD the audio goes out of sync, only by .5 seconds at first and then gets progessively worse to 4 - 5 seconds. It's very anoyying to watch. If I leave it in XviD it's fine though. When trying to rip the audio out using BeSweet I get an error saying sync found after 10xx bytes every time and then when I try and put it back together it's out of sync. I have tried using Besweet, VirtualDub and RiverPast Audio Converter to try and rip the audio out properely, but it always comes out incorrect. How do I go about fixing this so it's in sync all the way though and doesn't get progressively worse?
