Eyetv Hybrid Or Others?

so guys.. many of you are going to let loose a groan that will kill infants somewhere on the other side of the globe but.. I searched and I couldnt find anything incredibly helpful. I am not asking about some sort of emulator. I am asking if there is a way to connect and play XBOX360 or PS2 to my black macbook. I know there is the eyeTV hybrid, but what is the deal with it only supporting games up to 50hz? or something like that? and so apparently that excludes most games? can someone please make this a littl emore clear and tell me if the eyeTV hybrid is worth buying for the purpose of playing 360 or ps2 on my macbook. Or if there is another way?

thanks a lot
