besides, i think with a bit of tweaking xvid looks alot better than nero digital, it looks way to soft and blurry IMO. But I think that your sync probs could be easily solved if you'd use dvd2avi to extract the AC3 and then use headAC3he to convert that to mp3, headac3he automatically uses the delay value that dvd2avi indicates in the filename (the_boondock_saints_delay 200ms.ac3 or something like that)
