Am using d2h for last 2 years. below are pros and cons
1. It is best dth for south india especially tamil people as most of the channels with good picture quality
2. Customer service is good at TN
3. Not much issue in rainy season, it will get disconnect very rare only compare to other dth
4. Cost is lesser than TS and ADTV (sun dth could be lesser than d2h, heard from friends)
cons.
1. Earlier d2h doesn't had per day add for alacarte, but now per day alacarte add is possible
2. Remote will work only for one year, each year am changing remote (rs. 150 local shop)
3. Less HD channels, ( am not big fan of HD channels, so it doesn't bother me)
