I an using videocon d2h since 2013 from then we never got any issue about any channel subscription and happy using videocon d2h.
Picture quality of videocon d2h is average in non hd channel and if you have led tv then subscribe to HD channel for experince in picture quality.
Sound quality in videocon d2h non hd is average and if you subcribe to hd channel then the quality can be awesome and if you have led tv supports dolby sound then you can get much better and awesome experince in some channel.
Service and support in videocon d2h is very good. You can get 24/7 support from costumer care number and from website also.
Videocon d2h is totally value of money because it gives many channel in the price range of 300 rupees.
May my review helps you.
Thank you.
