Welll, that doesn't say anything to me to be honest. Its good I hope?
What I ment was that I have read elsewhere that if you get an error while test burning it is (usually) not a problem with the discs. Otherwise the test burn should go fine but you will get the error while actually burning.
Don't have exectly the same error message but its "incompatible format" as well.
Is this bad discs as well? Or could it be something different, like my burner slowly dying?
