When i try and burn a DVD in Nero it says POWER CALIBRATION ERROR and when I try it Prassi Primo DVD 2.0 it just says it has quit with errrors. I have just appled the 2x firmware before this and all was working well until this.

Can anyone help me with this?

which firmware did you use? What blanks are you using? What speed were u trying to burn at? Try burning at 1x and see if that will work for you.

I have tried Traxdata disks and FWS disks, 1x and 2x. The firmware was on *******************. Lets all media burn at 2x.

What version of the firmware did you use? There are various #'s out there. As I stated in previous threads, people should stay away from 2.0

Not sure m8, this is the descirption A hacked version of the firmware for the A03 to enable 2 speed writing to all media and the link is here http://www.*******************/modules.php?op=modload&name=Downloads&file=index&req=viewdownload&cid=1

It is the top firmware.

I have firmware version 1.90 and it still won't work! Can anyone help?
