Hey, i just bought a Digital Research DVD burner. It supports both the + and - formats, but i cant get the - to work. I have gotten it to burn regular CD-Rs and DVD+Rs without any trouble what so ever. But, every time i try to use a DVD-R, i get the “Power Calibration Error”. All the DVD-R’s i’ve tried are Maxell, and i am really really hoping that this is the discs and not my drive. I’m using the bundled Nero suite by the way.
