Sorry if this has been mentioned before (I haven't yet come across anybody with the same issue).... so yeah since installing iTunes 7 none of my videos tv shows/music videos have been playing smoothly at all. they seem to be doing about 1 frame per second or something which is very jumpy and unwatchable. I'm rather dissapointed. I realize it may be due to my specs, but I have an eMac with a 1Ghz G4 and 512mb ram which isn't exactly terrible and the same videos play perfectly in Quicktime 7.1.3. Anybody in the same boat as I?
