Writing Movie Maker to CD hangs computer.

I have recently installed a DVD/CD burner. I set up a test movie with a
title page and approximately 6 pictures. To try out the recording, I clicked
"Save to CD." The whole system hangs up at "Performing final steps to make
CD ready for use..." The computer shows 10 seconds to go, but everything has
stopped.

Suggestions?
