Yes, I understand what is happening and why (now), but I think for
most noob's MacOSX should have treated ISO images differently when you
click on one and then click on the Burn to Disc button. It just does
not seem to be as intuitive as it should be for users that are not as
smart as you are (or I am now). ;-)

Well actually ISO is a partitioning scheme, which hosts a file
structure, which may be a variety of underlying file systems, like
MS-DOS and HFS+.
I have created many useless CD-R drink coasters while trying to
burn an ISO to a CD-R disc, because MacOSX often mistakenly asks if
I want to burn the "Contents" of the ISO image to the CD-R, instead
of burning the ISO image on to the CD-R and I forget that doing it
that way does not create a CD-ROM that can be read on other
computers. When I use OSX's Disk Utility and burn the ISO image to
the CD-R, I get a CD-ROM that can be read on any computer.
That actually doesn't have anything to do with the ISO-ness of the
dis image, but the way you'e burining the image….the first occurs
when you tell OS X to put a file onto a disk (the iso file) and make
a data CD out of it. The second (via Disk Utility) you're explicitly
telling the mac that the file in question is a disk image and should
be treated as such, hence the successful burning.
