I agree, potentially useful discussion for Poser animators. I think the problem you're seeing is that a DivX .avi is already compressed, so when you convert it to DVD format, which is mpeg2 if I remember correctly, you'll certainly get some noticeable artifacts. Compression upon compression, and different protocols, at that. Going the other direction, from a DVD .vob to .avi, you can avoid noticeable artifacts. It sounds like you're actually making VCDs as opposed to true DVDs, sorry if I'm wrong. Can anyone else help out, here?
