I am considering getting Dish network and I have a Sony 5.1 receiver. Does Dish pass through 51. DD audio? I do not have HD and will not have for in the near future but I would like to hear DD 5.1. Are there many non-premium (non-HBO, Showtime, etc.) shows that are broadcast in 5.1? I live in Houston and does anyone know if the local stations pass through the 5.1 signal for the networks (CBS,etc.)? I currently have non-digital Cebridge cable (not in Warner service area) and I want to go with either Dish network or Directtv. Thanks for your help.
