I have been using the DVR service of Videocon D2H for the past 2 years.
Here are my observations:
Pros.
Has a good HD service.
Has a good number of channels.
Very reasonable pricing.
3D ready DVR .
Cons:
Software is not good. There is lag while using it.
Support is not good. There have been times where I have complained and nothing has been done.
Website require revamp. No good way to navigate and there is no way you can check the status of your complains.
I would recommend this service but at the same time request Videocon to improve on the cons to be the best DTH service.
