What is the position for the three SPDIF cables that go into both the HD621 and the 861? I had it hooked up yesterday and was not impressed with the sound. It also played much, much lower in volume than playing it without the HD621 using the one coax digital cable going from the Bluray to the HD621. Somwething seems amiss.

Thanks,
Ken
