I mean Nero cd-dvd speed disc quality test. My MCC003 is tested by most of the burners and the overall comment is; it is very good. Also i wan to ask that there was a firmware version of 1.50 and it is withdrawn by asus. I found it do you advise me to flash my firmware to 1.50,currently it is 1.40.
Also i looked yoru scans it seeems pioneer 109 is a very good device. If there is no problem with in my asus ,it must be good as yours.
