Win2000 Burning Problems

I have a Windows 2000 Server Service Pack 3 (Build 2195) machine.My burning drive is PioneerDVD-RW DVR-104.
When i try to make a DVD-RW data Disc i receive an error burning.
With Nero ILLEGAL OPERATION …The same message i received for VOB (Instant CD/ DVD ver 5.2).
i have to make the project as iso image and then burn it with DVD Decrypter (Only for video DVD).This procedure is sucessfull.
Also any copy od CD / DVD completed syccesfully.
The problem is try to make a data CD/DVD disc.
Anyone with the same problem or know anything about that?

Thanks for the reading
