I was all set to do a clean reinstall of Tiger yesterday, and I put in what I thought was Disc 1. I was informed that no, it was Disc 2, and to please put in Disc 1. No problem, since I must have picked up the wrong one. I put in the other one, and I got the same message. I looked on the DVD labels and both said "Disc 2". Has anyone heard of something like this happening? I didn't pick up my MBP at a store, as it was a refurb, and so I don't have a paper receipt that I know of. There are two apple stores here, however, and I hope I can go down there and get the discs exchanged.
