Need more info in order to go further. What ISO files did you referred to i.e. movies or games? If it's games, then just have DVD Decrypter burn it using Mode, ISO, Write W and browse to your files location (if it's under 4.7GB). Other than that, I'm not sure what you're talking about.
Hi there, As mentioned by "alkohol", you can burn the .ISO with DVD Decrypter. Most if not all burning software will let you burn an .ISO to Media. VSO CopyToDVD, Nero Burning Rom, NTI, Roxio etc... Use good quality media, and burn slow. x2.0 or x4.0 MAX to prevent playback issues !
