InfiniteMac OSx86 - iShowU, Skitch problems

I've searched everywhere for this and I have three apps having problems and I think it may be related but I can't find any definate answer. When ever I use iShowU, iShowU HD it records my audio, and my mouse but everything else is black even if I import into another mac app. I've tried every codec available and it's always the same result. I think it may have something to do with my video card which is an ATI X850XT on which I can't get QE or CI to work properly. If this is infact the problem does anyone know of a workaround of fix for the problem.

As for Skitch when ever I try to do a screen catpture it crashes. But I can use the built in Mac SC utitity to take a screen capture and drop it into skitch and it works fine.

Thanks in advance for the help... Also does anyone know a good app to view .wmv movies...
