I thought maybe this was going to be a one time thing, but just now, I tried to put in a DVD (The Neighbor No. Thirteen) to watch and I heard the Superdrive spin the DVD, read it a little bit and then after a lot of whirring and moaning as if it was going to read, spit it out. This is the second time this has happened. I tried to play another DVD the other day and this time it didn't read it at all and actually didn't spit it out until after I hit the eject button a million times. Both DVDs played fine in other DVD players and the Superdrive plays other DVDs, so I'm thinking that there may be something wrong with the drive itself. Any clue?
