How loud or noisey is your MBP C2D DVD drive when in or eject optical disk?
my mpb have big noise like bzzz-zzzzzz-zzzzzzzzzz rrrrrrr when in or eject disk
Yeah, that noise freaked me out as well. I had a good lucky streak with Macs so far (no lemon) and I was worried I had hit a jack pot of the lemon with my 15" MBP.
It turns out to be that is how the optical drive operates normally. I tried a few DVDs and no problem with watching movies.
