Ok, if the file you downloaded has an ".iso" extension, just do the burn image way. It's the only way it will work. When you say "extract" the iso, you mean you extracted the individual files from the iso file and burned them? If so, dont do that, just select the single iso file and burn it as an image. That's the only way it will work. You may think you're only burning a single file, but an iso image works differently. Nero will "extract" the individual files and place them on the cd correctly.
