I've never burned an iso file, why is it used. I just copy the files over to my pc from the xbox and burn them as is. Then I load the .xbe from boxplore and they always play. Why is an iso needed? Please don't flame I just don't know why you have to go through the pain of creating and using them

It isn't 100% necessary but it does seem to produce better results for more people. I know that everytime I try and do it via individual files it is hit and miss but if I convert it to an ISO and burn with DVD Decrypter, I get perfect results 100% of the time. It does varry from person to person though (with how well the individual files method works).
