[conspire] is there a minimum size iso that cdrecord will successfully write to a cd?

You should (ideally) always verify that your ISO images will mount 
using the loopback options before burning them.  Note that you can
perform this test only as the root user:

$ su -
# cd /tmp
# mkdir mountpoint
# mount -o loop -t iso9660 /path/to/name.iso /tmp/mountpoint
# cd mountpoint
[Look around, make sure everything seems OK.]
# cd /tmp
# umount mountpoint
# exit

If everything seems OK, and yet your CD comes out wrong, then there's
something wonky with the burn process.

However, I suspect you'll find during the loopback mount that you've
inadvertantly forgotten to include stuff in the pathspecs you passed to
mkisofs.  (That's what the test's for.  ;-> )
