i backed up my iPhoto library using the finder's archive folder feature. the zip was burned to DVD. now i've copied it back, the disc was kept very carefully, and there were several copies, and each one says it's corrupt. Windows & WinZip can't open it, and it's 2.72Gb. I'm really really pissed, but don't want to spend huge amounts of money on getting it open. is there any way to see inside, or to extract them? i assume it's happened because of the 2gb barrier on DVDs, and that it's more than that. which i never checked before, stupidly. can anyone offer any advice or help? thanks!
