I have a Late 08 MBP and recently I have been having some strange problems with my drive. It won't read commercial disks (DVD movies, software CDs etc..). It just spins for a while and pops them out. However if I put in a bank CD or DVD, it will read it fine and allow me to burn. I can reuse those discs time and time again without any issues. Could the drive be failing? I just find it weird that it won't read factory pressed disk but it can for blank ones. Thanks.
