well IPTV set top boxes are surely different from dth set top boxes.you cannot really tell how much they are worth unless you are an industry insider. the point is. airtel is promising features which are not really available on dth... if the service is good, they are a pretty good alternative to dth. and coz it is cable based, it has its own advantages and disadvantages. they also happen to be the only provider offering delhi aaj tak. which is i need. its not available on any of the dth services.airtel has a reputation of charging more than the other players. but they also have a reputation of providing much better services. and they do have a customer support that actually works.
