I created a disc from Star Wars Knights of the Old Republic disc one to use as a run disc when playing the game and it does not function. The message I receive is that I should insert a disc that is not a backup copy. My problem with this is that I made a copy of the Oblivion run disk the same way and it works fine. My question is "Do I need to have a decoding program active when I am creating the ISO image and if so what is a good program to use? I have DVD43 and it does not seem to react when I insert disc one to create the image." Thanks for any information anyone has that will help.
