ok my 5 month old pb is really starting to piss me off, its little annoying stuff like safari closing unexpectedly and lagging streams of video. you would think this new mac would be able to run heavily animated flash videos and streaming video with no prob. but what do you get??? sound that doesnt sync with the video, its ike im watching a kung fu flick!! im thinking it must be the browser, so i switched to firefox, whadaya know! same thing!!! to i pulled out my 3 yr old pc (see specs below) and it played these videos without a problem. no lagging at all! and thats my BS computer which is cluttered with BS! it probably has more viruses than a dying child. if macs are supposed to be "virus free" then why cant it keep up with my olds ass pc, i never had to verify disk, repair permissions or anything with it. what i want to know is is it just my mac? or are you guys having the same problem. and if anyone knows how to solve it, please help!
