I have a question that I think I already know the answer!! Does the superdrive have the capability to use RW?? I want to back my computer up and move from CDRW -->DVD-RW. I dont think this is possible is it? I think its jsut a DVD-R drive?? Thanks Also, this is a quote from Macfixit.com Power Mac G4 and AppleVision 850 James Macak writes: "My PowerMac 933 arrived with a bad SuperDrive, however, I did discover that the video card worked perfectly well in driving my old AppleVision 850 display to all its various resolutions." How was this known?? By trying to burn a dvd? I ask because I am about to get a dual ghz powermac + want to make sure it all works.
