I have an Onkyo 806 which isn't 3D compatible. Someone correct me if I'm wrong, but I think framepacked 3D won't pass through the receiver, but side by side content will. When I go to the 3D channels I have, I get two side by side images, then I manually change the 3D to side by side on my projector and it works. So perhaps your DTV 3D channels are frame packed. And yes, my satellite is hooked up via hdmi through my non-3D ready receiver. Hope that helps. Worst case scenario is you hook up the dvr directly to your tv, and then hopefully your dvr also has a toslink or digital coaxial output for 5.1 audio.
