I have a Mac Mini running 10.5.8 and the latest version of iTunes, 10.6.3. I used to be able to burn music discs at maximum speed with no problem. Lately when I burn a disc, my CD player won't read it. (But the Mac Mini will recognize it as a music disc.) Over the years, I have taken many suggestions to improve the stability of burns. "Only use Verbatim discs," someone said. OK. And yes, I am using CD-Rs, not CD-RWs. "Slow down the burn speed," someone said. Yep. That worked for awhile. But now it's not working. Any ideas or suggestions?
