I tried to burn a music playlist to a CDR today and itunes didn't recognize the blank CDR, I tried several, and then it started not rejecting the blank CDR. I had to shut off my imac and hold the mouse button down while it rebooted to eject the CD. I also tried to restore my ipod nano, at first itunes recognized my ipod and started the restore then part way through it just stopped and didn't show my ipod was recognized anymore and I had no way to eject it. Can anyone help with this?
