buddy just take the highest pack and enjoy all sd and hd chs. dth ops have to pay heavy amount to hd chs for every hd ch so what do u suggest should dth operator keep increasing price of hd pack then will u all b happy. the safest way has been worked out that tata sky has entered into agreement with every broacaster which runs hd ch and also has a sd counterpart that if a cust opts for sd counterpart of the hd ch then they dont have to pay heavy price for hd channel from that broacaster. so wait n watch when tata sky adds many more hd ch u will know why this policy is great. this hd policy will benefit all broadcaster, dth operator and customer
