Tata sky and dish tv both are not good at all.Videocon is far better service plus picture clearance and they cover wide range of channels .you never get bore but in dish tv their is repetition of movies every week .dnt take connection of it .itz rubbish .no real time recording feature.
You cnt change channel after you set recording on one channel.in tata sky this feature is present.my preference goes like 1st tata sky bcz it has real time recording feature, 2nd videocon n I will not suggest dish tv at all.
