Except I use a BenQ 1640 for quality scans, and this drive is fairly respected for it's accuracy in a home environment (as opposed to professional grade benchmarking equipment)
I will say that my Optiarc 7240S compares relatively well with scans from the BenQ once you understand there is a fudge factor involved. Bad scans are bad scans in either drive. And I have scanned every single PrintPlus disk I've burned.
I agree about not relying solely on disk scanning for determining whether a disk is playable. Some in MyCE look only to a smooth Transfer Rate Test for playability. I have not had a JVC/TY PrintPlus DVD-R or CD-R not play in any of my players so far. BUT, the longevity of the data must be suspected when disk quality scans have such high PIF's, especially those bunched together to form a solid line on the disk quality scans. That's troublesome.
I have never had as good a result with DVD-R as I have had with DVD+R in any of my burners. Still, performance of these PrintPlus DVD-R (and a spindle of variably performing DVD-R TYG03 Silver Inkjet) are the worst disk quality scanned disks I've ever had from Taiyo Yuden, and may be the worst I've had including some really crappy TDK that was over a year old that came with an optical drive I purchased on eBay. That's bad.
Like I said, I hope my disks are just a bad batch or a batch at the end of the life of the stamp/template pressing the disks in manufacturing, and future spindles will perform more to expectation of a TY disk. Otherwise, Taiyo Yuden is toast.
I now have better disk quality results from Verbatim DVD-R and DVD+R printable matte surface than these PrintPlus disks. This is a first for Verbatim consistently outperforming Taiyo Yuden in any of my burners. I can get Verbatims at the local store and the cost is comparable and sometime a few dollars less.
I'd rather have a better quality burned disk than a prettier one whose playability will fail much sooner. Time will tell if Taiyo Yuden is still serious about exceptional quality disks.
