honestly speaking dont bother about HD.its pure marketing gimmick.these buggesr (airtel,videocon,relaince,tata),they charge premium for normal sports channel and they want to charge more for HD broadcast.
many times signals are encrypted and they dont allow occasional recording of some real good tv srial or anything.
i am also of same opinion that cable does better than dth.
thats best thing.
no encryption no zanzat.
you can record if you feel like.
they dont cut your connection if you forget to recharge dth.
they give you better package if you pay for a year.
last but not the least,you can catch hold of your local cable guy if you have any issue.
regarding these buggers(dth), your luck decides on when engineer will turn up at your place if something goes wrong.
I am going to through out Airtel DTH moment the validity is over.
another marketing gimmick is a la carte.
no matter how few channels you watch,you are charged 150 rs per month minimum.
Get Normal Cable and get done with it.
