I don't know if anyone runs into the same problem as I do but, I seem to have compatibility issues with my drive. In regards, I am unable to use Princo Branded DVD-R/RW on my drive. Using nero 6.0 I get an error Message say "Power Calibration Error". Even when using other Burning Programs I run into the same problem of the Drive rejecting the Disc. I have always ensure my drive has the lastest firmware updates, (currently its 1.0d). Can anyone help me out?
