well, what got my wheels turning was this review about the 10pack
Not same as 3-pack Verbatim (correction)
Comments: These may have the same media ID as Verbatim DVD+R DL 3-pks, but they aren’t the same. I’ve seen consistently worse quality with the 10-pks. In Nero DVD speed, 10-pk media gives quality score of 82-88… More Â»
while 3-pk gives 95-96. PIE max is 62-79 with the 10-pk and 14-16 with 3-pk. PIF max is 17-19 for the 10-pk and 7-9 for the 3-pk. I’m using Pioneer and BenQ drives with BenQ for scans. Don’t get me wrong. The 10-packs are still still pretty good and better than the competition. But if you want maximum quality, get the more expensive 3-pks.
so I thought the qualified thing meant higher quality media.
