Okay so here's the deal, I bought this iMac G3 about six months ago and it is amazingly fast. I'll admit it's no road runner but it still packs a punch for it's age. Anyways, I downloaded the latest version of iTunes that is compatible with my machine, iTunes 8. Whenever I use the visualizer, it plays back really choppy although when I use the same CD in iTunes 2.0.4 on OS 9 it works fine. Any suggestions?
