The ECC setting is 8, and the disc is read starting at 4x, ending at about 8x.
The disc is readable, absolutely. TY should perform (a lot) better though. :a
In CDSpeed test it shows a nice smooth curve, again from 4x to roughly 8x.
Using a RICHOHJPN01, and setting the booktype to DVD-ROM, KProbe reads the disc from 8x to 16x (!) at the end and giving a rather nice constant PIPO of 32/3 - five times less PI errors than the TYG01, at more than double the speed.
What I'm trying to figure out is whether the TY are a 'relatively' bad batch, the LTD 166s reader doesn't appreciate them (it does do other -R fine, which was my first check), or if the NEC 1300a dislikes them.
I know there's no need for concern about data-loss, but if some ghetto Princo's do better, one starts to wonder...
