Sun direct is the first DTH player to bring High Definition to India.
Even thought they are just offering two channels at the moment. It will surely get bigger once others start launching their own system.
You have to buy a new HD capable box and pay for installation charges which means new Dish.
According to their website the HD settop box will be priced around
6200 (HD box) + 2750 (Installation charges) + 1200 (Two HD channel charges) and extra for other channels.
Look forward to paying 10000 Rs to get two HD channels which are in Telugu and Tamil.
I am not rushing out to buy this, i will wait for when Tatasky will bring Hd settop box with recording capabilities.
At the moment i am happy with my Tatasky+ which will cost you same as this. But will give you lot more features.
