I've got a Sony STR-DE885. The inputs on the back are marked specifically for individual components (ie. TV, DVD, CD, etc...). Here's the problem; I'd like to set the VIDEO source to DVD, and the AUDIO source to CD. The reason for this is I have no optical in on the receiver marked for DVD, but I do have one for CD/SACD. I can make this selection manually by going to the receiver, hitting MODE next to the bottom right dial, and then setting VISUAL to DVD, and AUDIO to CD/SACD. Everything works fine. But I cannot SAVE that setting! It defaults back to original settings the second I switch to a different component. Any ideas how to save the settings as a custom Mode?
