Thanks for both of those answers. I figured it was from an original disk.
I think one last question. Playing these from the computer would be easier with a 2809 or a 3809 without spending $299 on a sqeezebox?
It would be easier if your computer was close to your receiver, but the analog output from a computer sound card isn't normally hifi quality. A Squeezebox or similar device receives the digital sound file from your computer and does a better job of converting it to analog with it's own DAC.
