Hi,
I am a new member here. Wanted to give my 2 cents on airtel hd dth.
Talking about clarity on Hd channels, i feel airtel is way ahead of tata sky. Even dish tv offers better clarity on hd channels compard to tata sky. I see pixel in moving pictures on tata sky hd channels and also less sharpness. Softness on the picture in hd is more.Feeling tata sky is compressing more. tata sky is over hyped just because they are adding more hd channels.
Audio wise, i feel airtel gives better dolby quality compared to tata sky in my pioneer home theater. Tata sky sound is more bassy and less clarity.
Fyi: i used a tata sky transfer+ box for a month before i changed to airtel due to the above mentioned reasons Previously i was using dish tv but changed due to lack dd sound.
Overall i feel airtel is superior in both hd picture ans sound quality.
