My current popcorn hour is hooked up to a HDMI receiver and a HDMI monitor on the basement system...so all is goodness.
Upstairs, the main floor receiver has HDMI, but the sony tube xbr monitor is component only.
If I fed a PCM audio signal over HDMI to the receiver; would it convert the video to component? The receiver is a Denon 3806, and has hdmi in but very little audio processing other than pcm on the hdmi.
If Popcorn Hour came up with something like that, and the Denon would support it, a new unit would be very interesting. Right now I have a Dvico 5000 with toslink spdif and component output hooked up to this particular system.
