The organization of DVD and CD media is physically different.Most software won't even let you burn a CD ISO image onto DVD media. I don't think if you did that the resultant disc would be readable, but I'm not sure about that.
Plus, there's no point, just stick in the CDR/CDRW media in your DVD recorder drive and burn it. The CD media is lots cheaper anyway.
