There is no best or worst DTH when it comes to Channels.
Most popular is Tata Sky and Dish TV. Better to stick with the bigger ones.
[Tata Sky HD + Tata Sky + Dish TV in my house]
I had this. It was good and cost effective. However I ditched it for the Sky HD.
Who told you Dish TV and Tata Sky are big ones ? I was using Dish TV from last 5+ years and now they are worst in customer care. Moved to Tata Sky HD+ but regret due to less no of channels, and purchased Airtel DTH 1-2 months back. will disconnect Sky HD once my one year term is over and buy Airtel HD.
There is no term as BIG with DTH industry. Dishtv promote 30+ HD channels, AFAIK count the actual channels they are providing in HD ? 5-6 lol Most are upscaled and looks bad with 52' plasma.
Regarding the customer care, every care is worst for you if your concerns are not resolved. So, taking reviews from others to know which customer care is best is also a bad thought. Dish tv bad for me, doesn't mean it will be bad for you.
Buy which satisfy your HD/SD channel needs. All are same in SD, except Tata Sky has better picture quality in HD, and Airtel has better sound quality. You cant compare dishtv,D2h for quality/sound with Tata Sky and Airtel in HD. (I dont know about reliance dth but their cc are horrible )
