I've been a Dish guy for a couple years now, so I don't post in the Directv forum often. I assist my landlord by advising new tenants about their TV options and making the mechanical rooms available to installers when they come. Yesterday, ATT/DTV was here and said they could install this new system called Directv Lite and it would only require one dish and could feed multiple units. He acted like this was a new thing; but hasn't something like this been in existence for years? Also, how does it receive power? There's no A/C going to it that I can tell...
