Fixing an MBP OSX Superdrive that's rejecting DVDs
A lot of discussions online give this solution for fixing an MBP Superdrive that's acting out or rejecting DVDs. 1. Switch off Mac 2. Wrap the thin screen wiping cloth around a thin visiting card 3. Insert gently in Superdrive for about 2cm and clean side-to-side (the lens is supposedly a little to the left). Unbelievable as it sounds, it worked for me too! Try it at your own risk, of course.
