Hi all, I've been having some trouble with iTunes the past week or so - getting extremely jumpy playback, sort of sounds like a distant crackling or popping noise. I've turned off all my applications and even ran 'top' in terminal to see if I could have been low in resources - no luck. I'm running on a practically new 1.25ghz powerbook with 512mb ram. This is quite annoying. I've checked my speakers also - and they are not at fault. Any ideas/suggestions would be much appreciated. -- Andrew.
