Will the HD621 work for me? ...

I use an 800 with HDMI for DVDs, and a Denon Bluray for Bluray discs.

The HD621 manual says to connect the three Smartlink/MHR outputs from the 800 directly to the 861 (which is how it is currently connected) ...

But if I do that then there's no Smartlink/MHR input left on the 861 to handle the Smartlink/MHR output from the HD621's Denon feed.

What am I missing here?
