Thank you all for your advise. I discovered by now that the problem is pervasive. There must, most certainly, be an upgrade soon. In the meantime, I have switched to OS 10.3.8 using older versions of iMovie and iDVD. I stripped everything but the pictures and chapter markers, and, you're not surprised, it worked famously. I will now instal all the assets that were in the original try and burn again using the older versions.
