DVDs that I burn don't work in DVD player sometimes
I have a Mac Pro from early 2008, and it came with a DVD drive (OPTIARC DVD RW AD-7170A). I have been able to burn DVDs with it using Toast in the past.
But lately, half of the DVDs I burn won't play in my consumer DVD player. I get a "Disc Error" message when I try to play them, and they won't load. It's an odd problem, since some of them work and some don't. I can't tell where the problem is.
Is there a way to test the DVD drive? Should I just replace it?
