Is CD write quality good with 451@US0N(GSC2)?



I have some CD media with ritek dye. but CD write quality is bad on CD beginning and ok after 10%(check kprobe C1/C2).I don’t know this is firmware issue or media issue.Does anybody try cd writing with GSC2 firmware?
(US0Q is bad for my some DVD burns, so I change back to use GSC2)
