I've only used one media code - YUDEN000 T02 - since purchasing my 1620 OEM. About 100 were from Rima.com, the other 300-400 were FujiFilm "made in japan", purchased at Best Buy in the Chicago, IL metro area.
Things started off great - exceptionally low PIE's & PIF's, CD Speed tests of 97-99 were normal for me. Lately, I cannot get a quality rating above 95 no matter what speed I burn at.
Often, I might have to try 4-5 times just to produce a halfway decent disc from the same ISO file.
Benq's QSCAN reports "not recommended" for every burn speed most of the time on nearly all the discs. Once in awhile, I get an OK at 4X, but rarely. I do not give QSCAN much credibility though as even my decent burns have always been reported by QSCAN as "not recommended"
Bad batch of Fuji's? QC deteriorating at TY? Still have about 150 of these to go, but getting really irked when half, or more, have really lousy test results, or I waste 3-4 discs trying to make a single backup.
Here are some burns from the past few days:
