first thanks coolcolors for your interest
yes, codeking shows an improvement.
the nero blunded with the drive. ver : 184.108.40.206
as I told it’s data/iso’s. the size vary from 3.5 GB to 4.37 GB
I think Maxell 003 are top quality media (don’t you?). I previously had a 25 cake of cheaps Daxon az2. the disc are readable but the quality is bad however with that media I didn’t notice problems at the end of the disc instead they have more errors at the beginning (???).
about the speed you’re right if I slow to 12x the problem decrease. May be I should try 8x. but it’s a bit dissapointed because Maxell 003 it’s suposed to be good 16x media and my drive should be able to write up to 20x.
may be, later, I could post some scans to ilustrate the problem
