Thanks for the replies. I have the audio bitstreaming to the Onkyo and it works great. I went ahead and just used an optical for the cable box, I'll have to get extended RCA audio cables or something for the Wii, no big deal. I'm more excited for the surround for my XBox 360 anyway.
I have to say, I'm blown away by the quality of this set. The sub is more than efficient, I actually had to turn it down. It's loud and crystal clear. I'm more than happy with this purchase.
How to Train Your Dragon and Avatar were the first two movies I tried out, they sounded pretty incredible.
I thought it would sound good, but not this good. For a sub $300 setup, I'm impressed.
