Will there ever be an answer? Hello, Apple?
Yet we cannot reliably burn a disc in iTunes. It works about one time out of 10. The other 9 times it sticks in iTunes either at "Initializing" or "Finishing" and the only way to get the disc out is to kill the iTunes processes using sudo from a terminal window and rebooting. Discs that result from this never have anything burned on them.
Yes, I've tried all the suggestions I've found including updating software, slowing down the burn process, changing and removing the gap setting, et cetera, et cetera. I can burn CDs all day with other computers in my house and other software. Why can't I burn a FRIGGIN' CD with this Mac and iTunes??? This problem (via Google searches) has existed in some form or another for YEARS. What the heck???
