thanks, I have tried SFC and microsoft fix it and registry checker and all kinds of things; then
I found that if I right clicked on the drive icon and clicked on "open", it opened. I then clicked on one of the tracks and it said "reinstall Itunes" which I did and it works.
I had tried another burning program which seemed to have upset the apple cart. I am wondering if I need Itunes now just to keep the CDROMs running. WTF
