I just replaced a ND-3500AG with a new ND-3520AW. One of the reasons I got the 3520 was for 8x DVD+RW. However using RICOHJPNW11, OPTODISCOP4, or RITEK004 I am only able to write at 4x max. DVD Identifier v126.96.36.199 returns 4x (max) write descriptors for each of those media.
I've tried firmware versions 1.04, 1.UF, and 3.04.
Am I missing something?
