2 weeks earlier I ordered Airtel DTH connection online., I was bit confused about the packs of channels they provide. so I called consumer care, and their assistance was very helpful. As per their company policy they provide 1 month subscription free and thereafter you have to pay. The quality of HD channels was superb. 1080p you can say. I was impressed but rates are also high for that. I also noticed that the hollywood channels and all the western(English) channels were not activated. so I decided to activate it for 99 rupees and later on I found that the free subscription for 1 month was reduced to 20 days.
Sound quality for HD channels is dolby digital. but for normal channels the sound frequency is not clear and stable means the volume goes on increasing and decreasing every 4 to 5 secs.
if you can afford paying For HD channels then its a good product for you. and normal channels are also good. as its not that big issue. I would say " Go For It"
