Hey I bought a New macbook aluminum a month and a half ago. I've upgraded the RAM(crucial 2X2) to 4gigs and upgraded to a scorpio 320gb hard drive...now to the issue's. Its been working like a dream the past week and a half and then last night videos on youtube and just videos in general (tried playing a DVD but ill tell you about that later) would get these wierd flickery boxes in them even how the OKAY button on some windows (how thier animated fading in and out of blue) were flashing a bit. So I restarted and it seemed to fix it for a while then I noticed happened just for a split second on a vid i was watching. My next problem is that when I put a DVD in the drive it wouldnt let me play it because of the region the DVD was in and my SuperDrive was Diff.? My Drive is set to Reg. 1 and it happended on a couple of the DVD's I tried to play. ANY HELP WOULD BE SO APPRECIATED!
