Unless you own a Dish HD connection at present, I believe this is from past experiance or just online browsing that you are giving this verdict. Otherwise if you are a present Dish HD owner (and not last year) then may I ask for some examples that led to your conclusion of the service being poor?
From my present ownership I can tell airtel service is very bad, dish tv service is very good and prompt and 24/7 support for all type of needs.
I joined their HD service when they had just started, and at that time the service was not that great. Even before HD, I had 3 dish STB's in the house and have been with them since they started DTH. Presently I have suspended all Dish services, only have kept one DTH non HD box. I clearly remember when they had started HD they had no support for 5.1 audio, took them a while to get sorted out.
what also irritates me about DIsh TV is that they were marketing upscaled HD channels as true HD channels just to stay ahead of competition.
