DVD-RW not erasing?

[frsrblch]

I was trying out my new DRD writer on some DVD-RW discs, and although the computer writes onto them alright, when I go to erase them, I get a message telling me that they aren't rewritable. I also tried to erase a CD RW I have laying around, and I got the same error.

I check to make sure there weren't drivers for it that I hadn't installed, that the DVD format is supported, and I read through the manual to make sure there wasn't anything I missed.

Does anyone know what I might be doing wrong, or do I have a dud to take back to the store?

Go into Nero and put the DVD files off DVD. Srz I donćt know good english so U might didnćz understand.

What software are you using?

I'm using Nero 7, it came with the drive.

I also thought it wouldn't let me burn a CD ISO onto a DVD, but that was discovered to be a PEBCAK error.

Edit: Would choosing "Finalize CD" cause it to lose the ability to be rewritten?

This can be closed now. I just need to do my erasing in Vista, because for whatever reason, XP doesn't want to.

As you wish.
