Can I burn a CD ISO to DVD?

"If the image is an ISO, most, if not all major commercial software can handle burning the image such as Nero or imgBurn on a PC or Toast or Disk Utitliy on a Mac.

As you are talking Fedora, you apparently can just Select DVD ISO image in file browser and and do a right mouse click to open ""with CD/DVD Creator"", the set your write speed. Full steps are here

As to the specifics of the question of fitting a CD image onto a larger DVD disk. Yes it works no problem, you just waste the remaining space."

"As long as the medium is writeable and has enough space for the ISO it can be done. However practically it does not make much sense.

Windows 7 allows direct writing of ISO.
I personally use ImgBurn."
