Short Answer : YES
Long Answer : Technically isn't an iso image file burnable onto just about any type of optical media, even blu-ray? it just is kind of a waste, burning a cd image on a dvd
It shouldn't be that much different. But did you select a DVD project, or a CD project? They are different in Nero express. If you have started a DVD project, I don't think it should ask for a CD. I am not a pro with Nero, though :-) and fellow these steps
if you CAN use NERO. its the best you know.
open NERO BURNING ROM. (NOT NERO EXPRESS).
click on ISO.
change nothing.
click on "OPEN"
select the ISO file, the file you want to burn to disc.
Or You any one of these buners http://iso.snoekonline.com/iso.htm
