Running a G4 (dual 1 ghz, 2Gig mem, GeForce4 Ti 4600 video card) and video plays very choppy for some applications, especially for sites like Hulu. Just hooked it up to my 52" LCD and it was REALLY choppy on there, which I guess I can understand, but not sure why it is on everything else. Right now all I have is a 17" acrylic, any ideas why its so choppy? Anything I can do to speed it up or am I just out of luck?
