I really didn't think about DVD players until several folks mentioned them.
Some of you may have heard me talk about my movie theater. It consists of a DVD player and a meeting projector. I hooked that DVD player into stereo last night before we started watching movies. I knew that at least one of my DVD players wouldn't play CDs. It wasn't that one. It is now part of the stereo with the video cable running up to the projector, rather than being up on the shelf with it.
So problem solved. Thank you everyone for the input.
