OK GUYS , i have got this writer too .. its Sony DW-G120a B2 ..now its one cheap writer .. i have got BENQ DW 1640 too which is an all time great writer..
now first thing i did after getting sony is that i updated its firmware from mys2 to mys3 .. i think i got it from
www.cdfreaks.com .. now all know that
SONY is selling either LITE ON OR BENQ drives with their faceplate..
so i already knew that it is LITE ON SHM 165P6S .. then i crossflashed it to LITE ON DRIVE and now using goodies like lite on's smartburn utility to overspeed media and some other stuff like hypertunnig etc .. now its working fine and no prob with any dvds.. i burns moser baer dvds without any probs ..
so if u guys are having any probs with it then u know their is a way out .. oh and whenever u need to rma it then crossflash it back to sony and claim the warranty .. if needed . .. and also lite on's firmware support is far better than sony's ... and now days it's even performing better than the benq ..
