I just bought a Sony DRU700A and having problem burning an Xbox ISO file onto a DVD-R... using Nero. I got the ISO file on my computer, but when I tried burning the image to the DVD. Nero 6.0 keeps saying I don't have the right disc. It's asking me to replace the DVD with a CDR. I did click the DVD button from Nero so I know its not in CD mode. Am I missing a step or two here? Can someone please point me to the correct way of copying this ISO file? thanx.
