I just got an HDTV-integrated TV, and am now considering getting the Dish Network. I have a regular antenna hooked right now, and it works fine. I even get some local channels in HDTV, and they look great. If I get regular Dish Network (without DishHD), will I still be able to get my local channels in HDTV like I am now, or will it make it worse by making all of my channels analog? If it's the second one, can I use my antenna for local channels and then my dish for the other channels? I don't care whether I get the non-local channels in HD. Thank you so much.
