I thought I had this figured out, but after reading a few recent posts, I need some clarification. I am purchasing a Toshiba 57HX81, and plan on subscribing to Dish Network for my HD signals. I know I need the 20" Dish 500, an 18" dish, and the 6000 receiver, in order to get all of the available channels. I live in the Detroit Metro area, so my local channels (ABC, CBS, NBC & FOX) are available over the Dish Network satellite. Will I be able to receive the Network HD broadcasts through the satellite in HD format? Or, will I have to purchase an 8VSB module and an OTA antenna? Thanks in advance.
