I recently bought the new 13" Macbook Pro and I tried burning a playlist from iTunes using a Sony CD-R 700MB. I burned one CD a few days ago and it worked perfectly. I tried burning another again today and iTunes had problems burning the CD and ejected about 5 different CDs. I even downloaded the Burn app and it still does the same thing. It starts burning for a few seconds then says its finished. When I opened that CD on iTunes it had the amount of songs I burned except without any info and it didn't play it either, it just went straight through every song. Any suggestions?
