DH-16W1P and Nero 8 with Vista 32 - Cannot burn DVDs
I hope this is the right thread…
I have a DH-16W1P in my Packard Bell PC, and I cannot burn a DVD. I am using Windows Vista 32, and the latest version of Nero 8 (Purchased recently on advice of Retailer!)
I have tried the Flash/EEPROM utilities, but I still get the same errors: Either “Power Calibration Error”, “key-Medium Error” or just chucks out the blank (Verbation DVD+R) discs and saya "Insert a blank disc.

Any help would be much appreciated, we are going mad here!
