I just got a 57" wide screen from sony that is hdtv compatible (currently get hdtv over the air). Do I have to buy a certain receiver and dish (direct tv) to get all or any channels in the 16:9 format (hdtv not required but definitely a plus) or is this just wishful thinking? I currently just have a roof antennae and I need more channels soon. But I really love the fact that all my local channels send out a digital signal and almost all of them send them out in a 16:9 format. How do I retain this status with direct tv?
