I received the MCE remote. Love it.
It does a wonderful job of controlling the external Scientific Atlanta set-top box (extending reception to include all the digital channels). The HD STB is still connected directly to the HDTV via component cables (so I can watch HD channels when necessary) and simultaneously outputs to the RCA in on the Hauppauge capture card.
Of course, the HD channels aren't viewable on the PC.
I wish I could easily switch between the coax in and the rca in on the capture card, but I can't. Not without re-setting-up the tuner and channel lineup settings.
If I could switch on the fly, it would make it easy to switch inputs on the HDTV back to the STB to watch shows in HD while the HTPC would record the show in SD on an analog channel. But I can't. Hopefully adding a second tuner will allow me to do this. I suppose this means I might have to get a second PVR250 card instead of the dual-tuner PVR500.
Or maybe I'll just wait until there are HD-from-an-STB input options available...
