As a followup to my earlier posting with the Optodisc W004 media, it also burned with similar quality and no POF's on my DW1640 BSOB.
Here's another media code (BenQ branded) in some serious pain with DL12 on the 4167B. I've posted a burn from the same spindle on the DW1640 BSOB to give you an idea what the media is capable of.
It also burned some low end Kodak DVD+R media (AML 001) very badly in comparison to my PX-716A 1.09, results are attached.
On the positive side, I will say that this drive does handle non-TY media using the TYG02 better than most any drive I have seen.
