I should add that the DVD drive plays commercial music CDs just fine, and executes program CDs just fine.

This is a new (almost) Compaq EVO WD4000 workstation, running WIN XP PRO.

I had thought that I had recorded a test CD, with four songs. It now seems clear that I recorded nothing, and I was playing back from the hard drive or memory. Thus the failure of the music to play back automatically on insertion of the CD is understandable: It was either not monitoring the drive and/or the disk was still blank.

Any thoughts?
