Well evertime I try using the crop function while captureing to a DivX 4.01 using Virtual Dub, it comes up with a message saying "Unable to start video compression error: bad format (-2)", whats this mean and how can I fix it, also when I capture using Divx 3.11alpha it doesnt seem to render (smoothen) the video at all like 4.01 does, how can I do this with 4.01??
