Hello. My problem is: nero infotool shows that my mitsumi cr-485gte writing speed is only 40x,so i canot write faster with nero 6.3. Also in the XP the driver definition is cr-48xGTE. What is the problem?
It sounds like the drive is limited to 40x because it doesn't think that the discs you are using are good enough for higher speeds. Try some different discs.
