Microsoft invited us, with a few others, to tour the eHome team office and lab's and of all the great things we saw -- pictured in the gallery -- the one that got us the most excited was to see the rumored DirecTV HDPC-20 USB tuner in action. Our dreams were a little dashed though, as we were reminded on numerous occasions that although Microsoft tests lots of hardware, not everything makes it to market. So in other words, the presence of any hardware in the lab is no way an announcement of future products. But this here tuner wasn't the only thing we saw, as there were even a few indications that DISH Network was being tested as well, and while we did see DISH multi-switches and a DISH TV screen up on a Media Center PC, we didn't see any specific DISH equipment connected to Media Center. This could mean the tuners are internal or maybe the tuners were just cleared out before we came through. More pictures of the HDPC-20 in action after the jump.
