This one was a weirdie. It seems that, when Win XP gets a string of errors reading from a CD or DVD disk, it downgrades the drive from optimal DMA status to the slow, horrible PIO status so it can read "slower." But it never recovers. You have to run a little script and reboot your computer to reset it. I lucked into a web site that explains it: http://winhlp.com/node/10
The most common cause for this happening is a dirty or scratched CD or DVD disk. Which happens to a lot of disks, no matter what care we give them.
