In my view Ranking should be like this.
1. DishTV (Only for its affordable price)
2. Tata Sky (It would be on No. 1 for its service. But, it's price is too high)
3. Sun Direct (Bcoz, it's growing up day by day and week after week)
4. ADTV (For its services and clarity)
5. Videocond2h (For heaving at least more HD channels then, RDTV)
6. RDTV (as we all know what it deserves)
DD Free Dish deserves to be on No. 1 for providing Best services with no monthly rental. It beyond No. 1 it's on TOP
