The way it works is, each input has its own settings. Ideally you'd have two unique sources for dvd/cd. So if you play a cd with one setting and then switch to your dvd player, it'll be set to whatever your dvd was the last time you used it. Now since you're using your dvd player to run cd's as well, I believe it will simply stay in whatever mode it was in previously.

I just had an interesting thought which I may try out. You can select the digital input for your various sources. I don't know as I just thought about this while typing, but if you can set the same digital source to two different devices, you could have the dvd setting for surround, and the cd for whatever you prefer.

I may try that out just to see if it works. Anybody else try this? Does it work? Or once you pick a source for your digital in, is it not available for other sources?
