Awesome!! I recently got a Sony STR-DG1000 with the same capability.
And you are so right about the PCM sound.
Did you have issues with trying to connect your hd-dvr to your receiver? I noticed that you have it as component/optical. I tried to connect mine, and it had hdcp issues and wouldn't let me. Nevertheless, I noticed that the receiver's hdmi connection to my TV actually improves the picture quality than if it was going from the dvr to my tv via component directly.
