Not sure if this is normal or not, but if I have a DVD (Only tried with a blank DVD) inside of my MBP, it will auto-eject whenever my MBP is turned on. Also, when I went to install Windows 7 via Bootcamp, I had to tilt the MBP on it's side so the computer would recognize the disc. Could this mean I have a faulty DVD-Drive? The tilt thing only happened with the Windows 7 disc.
