Okay guys.. All i want to do is make awesome realistic-looking videos like moop's Colours. It's just an example of the graphical issue I'm having when activating a shader mode. First of all, watch these two videos to see what I'm talking about:

Colours - Moop

Wonderland - Shockwave

For those who don't see the difference: I'm talking about the joints and the realistic look of the players. I think that's ambient occlusion as a shader mode which doesn't work for me. Watch this pic to see for yourself. And no, it is not edited. The black squares you see is Fluid Blood, which doesn't work either. And the players you don't see is Ambient Occlusion. I have absolutely no idea what is going on and I really need some advice.

My System Profiler says:

Mac mini

No idea if this helps you but that's everything useful i could find so far.
