Oh just thought of one thing, you may want to go into the settings for your blu ray player and your cable and make do make sure you are not sending sound out over your hdmi... if you didn't you may be getting sound through the tv and through you avr if it did send it out over both and you wouldn't want that... again, me with a projector I don't care if sound gets sent to both my avr and my projector because my projector wouldn't do anything with the sound anyway as it has no speakers \:\)
