Origionally, I had to use iPC Live to do my install of OS X. Thanks to Windows software being stupid, when I did a system restore, it was done over my OS X partition instead of the proper drive. iPC Live wouldn't re-install, so I used a different ver and now I'm running Leopard.

Here is the problem. OS X cannot mount DVDs when I put them in the drive. I also have tried a CD that has Windows and OS X software on it.

When I did the OS X install, I did it to an ATA drive, my DVD is SATA and I don't have any choice on the matter. To do the install, I had to pull my other ATA HD and put in an ATA DVD.

What can I do?

I was told by a friend that it might be drivers because the drive is good on Vista. The model is HL-DT-ST DVD-RAM GH15L
