So I popped in a Verbatim DVD-R on my iMac, burned it, and put it into my MacBook later. The MacBook chewed on it for about half a minute, then spit it back out with no messages or anything. I tried again...same result. I put the DVD back in my iMac and it read it without a problem. I put an older Memorex disc in the MacBook, and it was recognized just fine. Tried another Verbatim disc, just in case the first was bad...nope, the MacBook will not read it. I would understand if this was cheap stuff, but this is Verbatim 16x media, it's pretty good. I thought we were past this crap. I haven't had DVD/CD compatibility issues on other computers for years. This really irritates me, because I have over 50 of these Verbatim discs, and now I'm going to have to reburn things on the old, slow Memorex 4x media. It seems really odd that a modern computer would not be able to read major-brand media. Has anyone else had this problem? I don't supposed there's anything I can do about it, like some sort of undocumented firmware update for the SuperDrive?
