Does that mean that it's not possible even with being modified?
If so, what about a 1.25 firmware (auto bittsetting SL+) with stock write strategies but with riplock removed and RPC1? I have noticed a lot of folks with similar requests....
Not to say we don't like the custom ones either, keep them coming! Since I only use TY DVD+R (and a few Verbatim 16x) I am happy with the results I get with the stock firmware.
I for one don't understand folks wanting miracles out of cheap media. I have always been very picky about my media even for CD-R. For example Fuji TY (both CD-R and DVD+R) can be found for near the same price as cheap crap in many stores. Why compromise? (ok off soapbox!)
