Ok, I missed the post asking why I was trying to burn the live-cd ISO.
I didn't see that in the name... Therefore I didn't know it was an
issue.  Meanwhile I downloaded another image and finally found a
bugzilla which said the problem was related to checksum generation for
the image.  I turned off the checksum and was successful in writting the
DVD image, but the system I wanted to check would not boot from its DVD,
due to a bios restriction.  I then came back to my system and attempted
to burn a cdrom, with no success.  Then I added K3b to my system and
used it to burn the cdrom, and succeeded.  It appears that brasero has
some fundamental problems, and the error #12 was returned in all cases
of trying to burn the image, and the image would not work.

However by turning off the checksum plugin of brasero, I was able to get
a dvd and by loading and running k3b I was able to get a CD, so I now
have both, and a lot of "junk" disks which brasero never finalized,
which I have tossed out.

I'm a dim bulb when it comes to these cd and dvd formats, so I will look
up the differences.  But I do realize that the raw form of the iso image
must include the disk structure, so it would be unlikely to work.
