Just digging in my desk draw looking for a CDR to burn a 32bit Ubuntu Desktop Edition iso (ubuntu-11.04-desktop-i386.iso) to and discovered I didn’t have any. But I did discover a DVD+R.
So using Brasero (The Gnome ISO Burner Program under Linux (Fedora 15)) I burn’t the image to the DVD+R and tested it by booting from it to install it.
I can now answer my own question — Can you burn a CD ISO to to a DVD-R? Yes!
I have also used imgburn on windows to do the same thing
Good to know. I’m a cross platform sort of guy so knowing that the same can be done on Windows using http://www.imgburn.com/ helps.
