FYI, I put the DVD in a better system and it verifies correctly. I suspect the problem had to do with trying to use it on a 1.7 GHz Celeron with only 256 MB of memory and a fairly old DVD ROM drive. The question of how to verify a burn remains however.
Darrin,
I was thinking I might try the burn again at a lower speed. That might make a DVD the old system could read though that would only help if the DVD were the problem there.
Alan,
the verification step for the ubuntu disks is on the menu where if you put in those options you boot to the Live version which is where you do HD installs from. IOW, I don't think there is any way to provide those options before the integrity check. Hmmm, maybe you can if there is an option to cause the integrity check from that same command line. I'll have to check that.
Thanks folks for all the help (including making me use my brain :)

This is taken from a description of installing Fedore Core 5. Perhaps
it also applies in your case?
"There is apparently a minor bug in the installer causing some of the
installation CDs to fail the media test even though they are ok. If some
of your CDs fail, try again with "Linux ide=nodma" at the "boot:"
prompt. If they pass then, they are ok, but it's best to use the same
option when using them to install FC5. After installation, we'll remove
"ide=nodma" from /boot/grub/grub.conf when we add some other options."
