I use powervcrII with my ATI TV TUNER PCI card to record into DVD compatible MPEG2, the audio and video were in perfect synch but when I tried to edit the commercials out, the audio always came out of synch, I tried editing with everything from womble to tmpgenc to M2 edit pro but nothing worked. So I finally tried editing with powervcrII and it stays in synch. I dont know why this works, but in my case it does. Maybe it is better equipped to edit the files since the same program was used to capture them. This is just to help anybody who was having problems similar to mine.
