I am curiose how you get it to decode the Digital signals. I have my DVD player hooked up to the reciever through the Optical input. I've configured the Digital input to read Optical 1. I only have the system setup for 5.1 right now. When I play a DD 5.1 DVD it plays it but on the display it doesn't light up the DD icon. The only thing I'm missing in my 5.1 speakers is the Subwoofer. (just got the reciever this week and haven't picked up out a subwoofer yet, but its coming) So does this reciever automatically know what to decode or do you have to set it when you put in the DVD. There are all sorts of Surround settings, and some sort of Cinema on/Off thing I don't fully understand yet, also stereo switch (thats easy to figure out), direct, and DSP. All I want to do is have it setup to playback at DD5.1 whenever I put in a dvd with that coding in it. The manual isn't very help in this though.
