Curiouse, I'm *really* getting excited with potential new features, but.. I've got an HR20-100, an H20-100, and like, 3 old D11-100's. If I want to replace the H20-100 with a newer HD receiver, or even replace the SD D11-100's with newer receivers, is there any course to DO that? I mean, I paid for the H20-100 when I had it installed a few years back (paid as in, they charged me for the pleasure of getting it, as I dont own it). Just curious if there was any sort of standard route without getting nailed for a hundred bucks each time.
