I have a 722 and I finally upgraded the upstairs TV to an HD set. I'd been watching using the built-in modulator which was perfectly fine, but of course now I'm craving an HD signal upstairs. The way I see it I can: 1) Hope/wait for sling receiver 300 2) Hope/wait for the XIP receivers and upgrade 3) Use the component out and run it over CAT5e or CAT6 (not full HD but close enough for me). This means I'd be using TV1 upstairs, thereby forgoing "real" multi-room video. I'd also have to run sound. 4) Try one of the wireless HDMI extender options and hope for the best. (again, would lose true MRV) I also found a box that will do component to ATSC (digital OTA HD signal) over coax but they're prohibitively expensive (cheapest I found was around $550). Am I missing any options? Does anyone have positive or negative experiences w/ any of these? Thanks.
