I can not get the install DVD to work. I am running a G5 1.6 GHZ, 1.5 GB ram and OS X 10.3.9. Tried just about everything, but it will not open on the desktop. Tried a restart with it in the drive holding down the C key but it just ejects the DVD.
I can open other DvD's with the drive. It is OK. I purchased this from macmall in Dec, just got enough nerve to install it. It does have a few little scratches on it though. Could they have sold me a used one?
Doubtful. Either try to get a replacement or try to remove the scratches. I've successfully removed scratches from CDs and DVDs using liquid auto polish (w/o wax), an old cotton t-shirt, and rubbing from the center to the edge.
