Cap card Q&A

Hi got a new cap card today and I was just wondering if anyone has any advice on what I should set the data rate (ks per second) to for optimal performance,and what is the diff between DivX low and fast motion?.

Oh yeah when I try to cap Video of VF {ntsc} it comes out with no colour in ntsc mode,and in pal it has colour but it flickers any suggestions?

I'm using Vdub by the way,is there a better freeware to be using?,it came with Video Studio but the damn thing crashes when I try to boot it /versus/images/icons/mad.gif
