Sorry, right, if it barfs on that one, that's where you have to set tvnorm and vfr. When it *does* fail without specifying the tvnorm, it will have the framerate of the video in the output, check that to make sure you are using the right vfr value. This is why I always try running the script first without the tvnorm and vfr specified. I don't seem to have the sound-syncing problem, though the one exception was really strange: the video came in two parts, each 700 MB, clearly encoded by the same person, at least by the filename; encoded to SVCD, the first CD the sound was out of sync by a maybe half a second, the second CD was fine. Downloaded a different version of the same CD1, same out-of-sync. On my third try right now. Sheesh. Anyhow, from what I've heard from Tom Brinkman on this issue is that you are pretty much at the mercy of whomever encoded the original DivX. You might try changing your sources, maybe try MLDonkey instead. Prolly not as fast as the transfers from usenet, but I've pretty fair luck getting everything I want, and with that one exception, they've encoded perfectly. > If I could keep the dialog from being out of sync, I'd pretty much have > things cooking rather well.
