For some reason when I play PH2 on my mac g5 the video runs choppy and slow. I read there was a sound driver update which i installed, and it fixed it for the most part, but it still runs 'choppy'. (originally it would play the videos in extreme slow mo...)

Any advice on how to fix this problem? ie maximize the performance of this game? I dont understand why its running slow, ph1, gk2 ran fine.

thanks!!! and please help!!!
