Videocon D2H is being used for 5 years at my place. This D2h service is indeed very good in comparison to others like tata sky, dishtv, etc.
It provides a very good picture quality and provides HD service also.
Though sound quality depends upon the television . A collection of 450+ channels gives a very nice user experience and different channels of several languages. If we talk about about service & support then if user faces any kind of problems then its just a phone away. Channel packs are price reliable and easily affordable by anyone.
Sometimes the service lags but overall it gives a rich user experience.
