on the BD-R verbatim disc quality issues..

[ultramegaburningenthiseist]

i think my opinion/guess is that its prob just a bad batch. il most likely buy verbatim's branded media once Amazon Prime Day sales start, and then il test them if they are the same. i will also be visually checking them to see if they are using the same burning "die" even though its not. 

il also do some LDC/BIS scanning to see if they return the same quality or not. i usually save results to compare them in the future.

though im not worried since i also have some printable disks i bought like last year and i also recently bought the last spindle of sony BD-Rs and 128GB disks.

This is quite unfortunate. I have yet to see a DOA (Dead on Arrival) batch myself.
I bought 4 spindles of 25 containing MediaRange BD-R SL (CMCMAG-BA5-000) discs, and none of them had any issues upfront, I could burn and properly verify them.

Have yet to see if the data on them is still properly readable or not after an year of being stored away but I have high hopes.

I would highly recommend you perform a Verify test on at least a few of those CMC discs burned a year ago.  Anything with CMC in its Disc ID generally raises red flags for low quality media.
