Copy a Data DVD?

[Banditt]

I am sure this is an extremely easy question, but how do you copy a Data DVD disc-to-disc?
I use NTI to create the DVD, but there d-2-d seems limited to CD.

Thanks

well i don't know what nti stands for. But a good program to use would be dvd decryptor since it is free. Save an image to your hard drive using iso mode and burn that image to the dvd-r/+r.

Nero has on the fly dvd-dvd copying.
