Yes, disc image(.dmg) is the same as .iso. If the file doesn't fit on a 4.7Gb disc then you will need a dual layer dvd disc. I don't know if Burn can cope with those. Disk Image will handle the large files as well, however, I often save iDVD projects as disc images, but when I've tried that with a project that would need a dual layer disc, I've had a message saying that burning dmg files to dual layer discs is not always successful, so I didn't proceed that way.
