Weird problem that I can't explain

[SilverBlade]

I have been using computers for years, and even have built my own, so I'm no dummy when it comes to PC's, but, this situation has me completely stumped:

When I try to burn an Audio CD, or an ISO image file in Nero, Nero gives me Power Calibration errors. But, when I try to burn an audio CD using iTunes, it works, and the CD works in my stereo. Also, when I burn a DVD ISO image using DVD Decryptor, it also completes, and I can play it on stand-alone DVD Player. I can burn Data CD's, but Data DVD's give me an 'Internal Target Failure"

My DVD drive is the Pioneer 110D, and I just purchased this in March, so I can't believe that the drive needs to be replaced this quickly.

Ditch Nero. Use CD Burner XP Pro for cd + data DVD. Use ImgBurn for Video DVD. All bases covered with freeware.
