    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?

    Hulu uses Flash right? OS X's Flash sucks so Flash content is choppy in PPC Macs.

    I'm not an expert but I know that all G5s except the quad had problems with h.264 in high resolutions like 720p and 1080p. The codec is optimised for streaming and efficient storage but it needs much more hardware resources than MPEG2. PPCs were generally not having sufficient CPU capacity to run high definition content based on h.264 in fluid motion. So the problem could be flash using that codec in higher resolutions.

    Much more detailed than I expected, thanks guys. Guess it is just the flash then. Ill try a dvd or something and see if I get different results.
