What if ADTV adds the rumored 3 SUN HD channels ? :lol
Then, I guess ADTV HD should be a better choice.
Also, SWP HD and may be MTunes HD cud be added, that way it wud be a better option than d2h HD too.
Airtel, is already way ahead in Tamil channel count, at par in malayalam, at par in kannada ( with public tv, it'll be equal with Sdrct )
d2h HD has 2 useless HD channels, in d2h active hd and cnbc prime Hd, they can be ignored.
Keeping south chnls ( i m assuming tamil), ESS HD, better pricing as key factors, my picks wud be:
1) d2h HD
2) ADTV HD
3) Dish HD
