Hello, I have a strange problem with my CD/DVD-drive on my MP. It only reads certain cd's / dvd's. The "not working" ones are ejected after about 5 seconds without an error message. When I tilt my MP in an angle of about 90 degrees, it also reads those 'broken' disks... It's, very, very weird. Did anyone else had an issue like this? My Macbook Pro is more than a year old, ordered it online. I don't think I can replace the drive under warranty. Maybe iTunes blocks certain bands from being added into the library. Thanks for your help & info!
