Please, let's stop this non sense of learning from Tata Sky and RDTV subscribers...
Subscribers are paying their hard earned money to avail the services, so its their right to demand for the best service. Its not a ritual or protocol or something, that subscribers need to go through a year long waiting period to get demanded channels, as if they are going to achieve nirvana after life long struggles. The market has provided us with a choice of 5-6 DTH operators, whichever suits best to one's needs, they should move to it.
Now, shifting to another DTH is kind of costly, for which it's high time they bring in DTH portability just like mobile number portability..
