Windows – Can Windows 7 burn iso images to DVD’s natively

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.

The max size of a DVD+R DL is 8,547,991,552 bytes...so maybe the person creating the ISO thought this meant 8.5GB, and created one that was too big?

Or if you ripped this from a commercial DVD, real dual layer DVDs can actually hold more than DVD+R DL's can.
