Thanks, I thought as much. That is, to stream movies, my HTPC would need a direct HDMI connection to the SPD-55. But I was hoping otherwise. I was hoping I could leave the HTPC where it is upstairs, rather than moving it to the basement, where the SPD-55 is intended to be.
There are lots of solutions to this. Your main PC can act as a server (stay upstairs ) and you can use a different PC or media box in the basement. The only reason I see to move the PC is if you have it highly tricked out for madVR.
