I have Toast 6 Titanium. I can't burn CDs, I put the cd in my Mac and a blank disc in my burner and when it gets to the point where it says, 'DOA writing line-in...' it does nothing, I sat and waited 23 mins and still no blue line just ' DOA writing line-in... '. It used to burn CDs for me, It still burnes files and programs. Any ideas ??
