Sun direct go has been launched and many people are saying it has the best picture quality since it is a digital feed without compression. so quick questions @Vadirocks @PowerStar
1)Whether the digital feed applicable for all channels or only sun group channels?
2)Does tata play/dish has comparative app like this which provides good quality stream?
