Yes, I have a USB tuner that correctly accepts off-air HD antenna signals, BUT, I want to connect an (HDMI or comp video) output from my satellite box inTO my computer so I can watch satellite HD on my computer screen. This actually works fine using s-video, but that doesn't give me "HD" in my computer. It seems that an "HDMI digital in to USB digital" adapter would be simple and useful, but I haven't found such a thing on the open market.
