I have a question in regards to the Multi Channel features on my Sony STR-DA5ES receiver and DVP-NC650C DVD/SACD changer. The blue light for the Multi Channel indicator on DVD works when I have my DVD or SACD playing in the DVD but the light does not come for the DA5ES receiver. I once had them both on at the same time and I don't know what happened to cause them not to be on at the same time anymore. Shouldn't they both be on at the same time when playing a Multi Channel disc such a SACD or DTS 5.1 DVD? I can recall that I had this working when I had an optical cable hooked up but was told that I should be running a coaxial cable instead. The coaxial cable would provide a much better connection and sound as opposed to the optical cable. What should I do to get this feature to work again? Also, shouldn't there be an on screen menu for my television? I saw this on an STR-DA3ES receiver in the store but mine doesn't come on. How can I invoke this for my setup. I have an older 32 Sony television but should be connecting my 36-XBR450 in two weeks when my new entertainment center arrives.
