Evening all, Seems like this has been a common enough problem but I can't find a solution anywhere. I copied some stuff from my DVD Recorder on to a disc (and let the recorder finalise the disc) and then put the disc in my iMac - as the title says, it tells me the DVD is blank, when it's not. Has anyone who has had this problem solved it? I had Superdrive trouble before and ended up having to reinstall Leopard (permissions problems, or something like that), really don't want to have to do that again. I've tried several different discs/brands, same problem. Any ideas? Thanks.
