I think my superdrive died in my dual-core PM G5. This is what it's doing: I'll insert a DVD and it'll sit for a few seconds, then eject it. It DOES show up in my system profiler though. Is it dead, or is this a software problem? Oh- I should mention that the last thing I did was use Visual Hub to burn an AVI to a DVD. That worked fine. Afterward- nothing. I'm running OS 10.4.9. Help!
