This morning when I tried installing C&C Generals, my superdrive spun the disc, made some weird noises and then spat it out. I followed it up with another DVD movie, same result. I put in a regular music CD, it spat it out. I put some blank media (CDR) in and it spat it out. Has anyone encountered this before? Is it fixable, or is it time to envoke my Applecare Warranty?
