My 13" Macbook DVD drive suddenly failed. I put in a movie DVD, the disk did not mount, the drive ejected it claiming the media was not supported. I put it back in, the drive ejected it, and thereafter continuously tried to eject a non existing disk. It does this every few seconds for several minutes before giving up. Opening disk utilities starts it up again as does waking from sleep or rebooting. resetting p-ram did not help. A disc cannot be loaded (the slot is blocked). Here in Japan, repairs likely to take 2-4 weeks....anything else I can try before biting the bullet? Macbook is 3 months old. Nothing else is faulty (except some uneven "hot" spots on the display).
