The title says it all. None of them are able to tell me the media codes and/or capable write-speeds. Oddly enough, Alcohol %120 -does- give me all the information and I could have sworn CD-DVD Speed initially worked correctly also.. Now, I -do- have 4.6 ASPI 4.6 installed and the BenQ DW1640 is DMAed and flashed with the latest (I believe) official firmware (BSMB). Any ideas? thanks, john
