I have been getting the dreaded "power calibration error" every time I go to burn a dvd. It is still working fine for cd - have tried everything - different media, cleaning the writer, disabling the IMAPI thingee, updating to the latest version of Nero 6, everything I can think of, and followed the advice in other forum threads regarding this problem. I'm fed up! Any alternative burners you can recommend - I only need something for dvd files. Thanks!!
