I THAVE TRYED TO COPY A DVD WITH MY NTI CD&DVD

Hello,
I would suggest that you should try out NERO Burning software instead. I have been using it for years and it works like magic.
Even if you just need something very urgent, you can download and use the trial version with the trial key.

It is a very self-explanatory software and shouldn't give you any problem when install it.

The link to the trial version is:

Kindly let me know how it goes.

Good luck.
