I'm not confusing the two. With a DVD, the ISO is burned to the disk.
You could always recover it via "cat /dev/dvd > image.iso" (or something
similar for your device name). Both are ultimately an ISO image. Only
the container (and as you said the actual mount options) differ. I
guess you like to split hairs.
