I'm not sure when this happen because i hardly ever use the superdrive. But Today i wanted to play Command & Conquer Red Alert 2 and it would try to read the CD then spit it out. Next i tried a music CD and same thing. But My 10.6 install disk and 10.5.5 OEM install disk work I also tried a DVD movie and that worked. I also tried a blank CD whitch that worked anybody got any ideas?
