a dishtv user could not adjust in tata sky or adtv bcoz of less no. of channel .
so only choice for them is d2h.
i am currently using d2h and adtv
d2h have very good customer supprt . i never faced any problem .since its first year of launch.
PQ and AQ od sd ch is not as good as adtv or ts .. but HD PQ is decent.
d2h has currently added two 54mhz tp so currently no space problem ..but remember ch addition is quick in dish tv..
only problem is that their stb are not up to the mark and the software is just a simple one..
but the biggest plus point is money.. it is cheap
