I just received my SR-HD500 in the mail yesterday, and upon looking at the box, I'm confused as to how it will connect to my Mits 65905 HDTV. I currently have a HTPC connected to the DTV YPrPbHV input via a 15pin VGA breakout cable from BetterCables. I picked up an Extron VGA switchbox ahead of time thinking that the HD400 STB would have a VGA output. My mistake for not checking first I guess. How do I connect both of these devices to my TV? Can I just get another VGA breakout cable and connect the HD400 to the VGA switchbox, then from the switcher to the TV? Someone told me that this would not work.
