Thank you pigoo3 and harryb2448.Here comes the silly questions.Is LionDiskMaker on the Lion system or does it need to be downloaded? I gather iDVD is not good for this job.There isn't that much on this machine, 50/60 photos, 20 odd music tracks, but any rough guesses as to what size memory stick I might need.And seeing I am making a plonker of myself here, why would the ML be removed from the Applications folder and I am presuming that that is not a bad thing? As I say, please forgive the questions but between not being very computer savvy and newish to Apple....Regards
