I think a neat solution might be to introduce a DVDO Edge into your system. Take the HDMI out for your TV source to the Edge, where you split off video and send that via HDMI directly to your display; the audio goes via HDMI to your processor. By selecting the audio input at your processor, you can decide what audio accompanies the video.
In my application, video goes directly to a projector, audio to an audio-only processor. What you see and hear is entirely up to you. And the Edge can do wonderful video processing.
