I assume I > could do the same for XVid/DivX files converted to .vob files. I have no idea about what you are talking .. :) I just use virtualdub for almost everything I do.. I've never played with .vob files.. I use some kind of app to create VCD on windows that makes the convertion.. VCDHelp, I think... I really hate windows and avoid it.. My w2k install in one of my machines is just returning lots of errors of wrong memory addresses being accessed and I'm not in the mood for reinstalling it.. The problem is the for I more that 3 months.. :) I use mplayer for extracting streams from video files .. mplayer is infinitely better than any windows player, as soon as you get used to.. :) > >I've beem downsampling videos to watch on my Nokia 6600 too.
