I have been trying to convert an xvid avi file to dvd using TMPGEnc Xpress 3.0. I am a relatively experienced user of this program, and have successfully encoded several very similar files into dvd, however when I try to do this particular file, I get a strange error. When I begin the encoding process, it immediately fails and an error message pops up: "Error: Divide by 0." What does this mean? I should also mention that when I load the file in VirtualDubMod, it is unable to decompress the video stream. Do I just need a new xvid codec?
