how to get new hd audio to theta cas.3??

since the hdmi upgrade seems far away how would you route the BR player thru the cas.3 to get the hd codecs?? I heard it is not that easy - i am thinking of getting one with 2 xtreme dacs but not sure how easy to get 7.1 Hd codecs= thanks
The only way you can get this with a CB III is to decode it in the player and use the multichannel analog, so you would also need the six shooter I believe to make this work. Sorry about the delay from Theta, @ CES they were saying they might try a separate decoding box like the Meridian HD 621 as they had some major issues trying to make it work in the CB III....
