Audio newbie so be forewarned.

So I have the SurroundBar 6000IHT and love the setup. It is perfect for my condo and sounds great even in the open area living space I have setup. I don't want to sell it and get a new configuration, but I want to be able to watch video with DTS audio.

Is there a way to put a receiver that supports DTS in between the signal and the surroundbar and still send 5.1 to the 6000IHT?

I would also like the get the wireless rear channel, I was wondering how I could add this to the 6000 setup as well.

Any thoughts?
