Thanks for this explanation. I knew that there were differences between the
CD and DVD portions but did not realize that two separate lasers were
involved. I makes sense that something is blown with the laser for CDs.
I tried some data DVDs and was able to read them OK. That reinforces the
idea of something wrong in the CD portion of the drive.

The whole computer is less than a year old, so it should be covered under
warrantee. I would prefer to not have to send my computer to Apple for
repair. I wonder if I can get them to ship me a replacement drive.

Yes, the Power Mac is a tower configuration. Swapping drives is something
that I feel comfortable doing myself.
