I have a MDD 867mhz Dual running 10.3.9. Yesterday I burned a music cd using iTunes and it worked perfectly. Later that night I upgraded to the brand new version of iTunes and now my computer will not recgonize ANY type of cd-media. I've tried blank cd-r's, cd-rw's, store purchased music cd's and some that I have burned myself. The drive doesn't spit them out as if they are unreadable, it just doesn't seem to pick them up. Is it possible that the new version of iTunes has messed something up?
