Videocon d2h provides their best service to their users.I am using Videocon d2h from last one year. Similarly we are also using Tata Sky at the same time.There is a lots of difference in service providing by the companies.Remote of the Videocon d2h have redar system which is very useful because you can use the remote from any where but in case of Tata sky you have to use the remote in front of Setup box to change the channel or for any other purpose.
Picture and sound quality of both Dish are almost same and you can enjoy High Definition channel.Both operator dish gives best picture quality.
Service and support wise both are also same because in rainy season both operator lost their signal and you have to wait for rain to stop and after that you can see whatever you want to see on TV.
Value for money is little high because if you are using HD pack then it is very expensive.Almost all operators plan are expensive as compare to your local city Dish operator.
