Anyone know about the 4000 range of channels? I help out at a local community access station and they have a commercial account with Dish. Free Speech TV is on 9415 for me and was for them up until a couple of days ago. They have a commercial Dish account. I called Dish and they sent me to 4379 and bingo! I have no 4000 series channels on my 922 at home. Are channel mappings different for commercial accounts?
