Thanks, everybody, for your suggestions. Chris nailed it, although I didn't see his message until afterward. As part of my strategy of "try everything," I booted up Windows on my parents' computer, and used Nero to make a copy of the pressed Ubuntu 8.04.1 CD at the default speed, which was either 40x or 48x. Then I rebooted from the new copy, and Ubuntu installed with no problems at all, and runs. (Although I didn't get to check out whether the installation can access the optical drive.)
So Ubuntu's installed, but I don't understand /why/ it worked. How would the copy I burned be any different from the one that Ubuntu pressed? And if there is a difference, why didn't the 8.04 that I burned on my own machine work there? BTW most of my parents' machine is from about 2004 if that makes any difference. Thanks in advance to anyone who can enlighten me!
