Calculation wise airtel PQ is less than D2h (which is cristal clear according to dino). bcoz airtel have limit of 38 SD in one 36mhz Tp so in one 54mhz tp of d2h no of channel should be 38+38/2 = 57 . (bcoz 36+36/2=54mhz). but d2h has lmit of 48 SD in one tp . so calculation wise d2h is supirior. but i do not fell any difference in PQ of airtel and d2h .. only SD music channels in d2h is pathetic .
colors HD in d2h is supirior to airtel . ( i have not subscribed enough channels so i only observed colors HD in bad PQ)..
i think Dino is now crossing the limit bcoz if airel has some channels in pathetic version then d2h has more channels in pathetic than airtel.
but remember all the popular SD channels in all dth are good .(same in airtel and d2h)
