TYG03 and YUDEN000 T03 like being burned at 16x
but hate being burned at 4x.
I don’t agree.
That depends entirely on the drive and firmware. I’ve had very good burns at “1x” (real-time recording) in a HDD/DVD standalone recorder with TYG03, and excellent burns at 4x in a NEC ND-4551A drive with YUDEN000 T03.
Regarding TYG02 in a Pioneer DVR-111, I would personally burn them at 8x or 6x. Burning 8x media at 12x will almost always increase either jitter or PIE/PIF and it’s not worth it for me. I have also seen many cases of a slight improvement in jitter by decreasing burn speed from 8x to 6x in NEC and Pioneer drives.
I have burned TYG02 at 12x in a Pioneer DVR-111L which uses a 6-8-12x Z-CLV writing speed. There would be no advantage in burning at 6x if your burner and media behaves the same way as mine, but burning at 12x increases the jitter compared to an 8x burn.
So I suggest burning at 8x for this combination of drive and media.
