Thank you all. Happy to know that Videocon is not having any HD access fee. So will be for Airtel too, i guess.
Without HD access fee, i think a-la-carte is better option to cut down the huge costs on HD channels. My wish is to have only couple of HD channels just for name sake - may be 1 movie, 1 music and 1 info channel.
If gone for Base SD pack+Base HD pack, here is the comparison list (South packs only): Tatasky - Rs.180+Rs.125=Rs.305. DishTV - Rs.185+Rs.125=Rs.310 , Videocon - Rs.180+Rs.100=Rs.280, Airtel - Rs.170+Rs.70=Rs.240.
Now, being selective, all D2Hs have a-la-carte rates between Rs.150 to Rs.165. But for Tatasky i need to pay extra Rs.125 as HD access fee. For DishTV, neither 'Pick My Channel' service has HD channels nor independent a-la-carte exists! So final options are Videocon and Airtel. But for Airtel the HD charges are couple of rupees higher than Videocon. Also, considering the HD selection list and the cost of the HD set top box, i decide for Videocon. About Rs.165/month only. Please correct me if i am wrong in my judgement.
