Zev,
I had this problem recently. It turned out to be the Apple CD/DVD
Driver in the extensions folder. Driver version 1.3.5 works correctly, but
the newer ones do not. I never got an "unreadable" message--I just got no
activity at all, then finally the disc just ejected on its own. Maybe this
info will help!
