Let me explain what I want to do, I OWN many DVD,s and I have 2 DVD Burners, and I want to be able to use Nero to BACK-UP 2 images to my HDD at a time, my comp is very fast so i know it can handle the load, mbut I can only run one instance of Nero to burn to its Image Recorder. Oh, and 2 burners are very useful, especially when making 1:1 dvd-9 and dvd-5 back-ups, eliminates any HDD use whatsoever.
