i give up with the first pack of 20 us ones, as straight after burned a us one with 1650 with bcic firmware and down to 78% quality , will just burn them with my liteon 1635s and be done with it not even going to bother scanning them anymore, may have better luck with the remaining unopened us verbs, whatever. got plenty of UK verbs now anyways, the us ones i have well first pack look substandard compared to UK ones, build quality wise like the glue in middle ring is smeared etc, UK ones are crystal clear and look better quality.
Out of my control they are what they are, like i said remaining 40 maybe better.
The scan has finished now and quality rating went down further to 73% burnt on 1650 BCIC and scanned on same drive.
LOL, it will still work so i can live with it.
