I just started burning dvd’s again after a couple of months (no time). To my surprise, my almost full 25 piece tub of Verbatim 16x DVD-R Glossy Printables (MCC 03RG20) has turned ‘bad’ during that period.
I have tried burning them with Benq 1655, Samsung SH-S182M and my brand new Optiarc AD-7203A (best drive I ever owned), at different speeds including 8x, 12x and Max, with disasterous results (from PIF spikes in the thousands to lots of POFs or even incomplete burns with errors).
The latest Optiarc burns seemed OK at first (Discspeed gave them scores of 98), but deteriorated within a few days to a point where I could only just copy them with my Benq (except for one disc). My Optiarc could not read any of them back.
These are MIT with hubcode MAP701KA02104482 B2. I did not even try printing on them.
