It's a SuperDrive but it acts like a CD-ROM drive! I inserted a DVD so I could burn a project on it, and it makes a few funny sounds then ejects the DVD. Doesn't find it or indentify it or anything, it just ejects it. And the settings for when a blank DVD is inserted is to open Finder, so it shouldn't just eject the disc. Anybody know what to do? BTW it burns and reads CD's fine, plays DVD's but just won't accept blank ones.
