I have a 2.4GHz Intel Core 2 Duo iMac running Mac OS 10.6.3 with 3GB 800MHz DDR2 SDRAM. Yesterday it burned a music CD in iTunes. This evening it burned a video DVD in VisualHub. My SuperDrive works. So why is it suddenly spitting out any blank CD I put in today when it was fine with them yesterday and it was fine with the blank DVD it used just minutes ago? I need help before I resort to smashing the bloody thing with my bare hands. Additional note, it reads commercial movie DVDs fine and is spitting out commercial music CDs (and has done on-and-off for months but still reads data discs) Does anyone know if this is a software or a hardware issue?
