I just got my MacBook Pro (actually two of them). I am trying to boot off the grey OS X Install Disc and I can't....I tried both copies of the discs. I can't even see the discs on the desktop. the drive jsut makes a noise over and over again like its trying to load it. Then it just ejects it. The discs feel physically thicker than most DVDs which may be a problem. I tried booting off a leopard DVD (retail) and it just reboots into the white screen. Anyone else have a problem with the restore DVDs?
