I own a 15" mid 2009 MacBook Pro and I have a unique problem that I can't find any answers to. The DVD player on the mac won't play ONE of my DVDs. All of my other DVDs work fine on it except this one. Every time I put it in the drive, the drive won't even read it; it would just make this a series of weird noises that I could only describe as a hybridization of a beep and a buzz; and without hearing the disc spin, the drive would just spit out the disc. At first I thought it was a problem with the disc but it works fine on my DVD player in my TV and my Xbox. Ever had a little annoying that drives you crazy, this is mine. Oh, if it helps out, the DVD is "Star Wars Episode IV: A New Hope" from the Star Wars Original Trilogy Box Set. Please Help.
