I used dish TV ,Videocon and now tata sky
Out of 3 the poor service is dish TV .. All HD channels are very much clear when it comes to home theatre its really bugged up with no Dolby digital output in many channels
When comes to SD its very very very poor
Videocon is far better than dish TV in HD and SD but sw is poor
Tata sky is ultimate in sound and picture quality
I can assure even it take 5 yrs dish tv cannot take over ts in its quality
Videocon have chance
