I've noticed something strange with YUDEN000 T03 (Verbatim brand) batch of mine.
My freshly obtained DVR-212 burns with excellent quality (I'm using latest 1.15 firmware), including above TY media, but only at x16 (didn't try x18 though). BUT, if I set the burning to x12, it seems that this media (or just this batch) with combination of this drive/fw somewhat dislikes P-CAV burning, and the scans get much worse after the "switch" point to linear velocity.
Scans were made with BenQ 1655/BCIB, burns with DVR-212/1.15
Only TY media seems affected, TDK003 works very well with both x16 and x12. Scans are attached below.
If TY media is burnt with BenQ or my older Pioneer - DVR-111, no such thing
Did anyone experienced such behaviour ?
