I think, all South Indians should bet on Digital Cable operators such as Hathway, DEN etc.
Since, the cable bandwidth is huge and the cost for bandwidth is nill (only one-time cost to buy cable and the signal boosters), a digital cable operator will be able to provide many HD Channels.
But, I think, hathway is also stuck with MPEG2 standard for SD channels, which eats up some extra bandwidth.
We are planning to move to our new and own house, so, we are thinking of a cable option, because of two reasons -1) bandwidth thus more HD channels (at least in future) 2) A single cable is sufficient to power any number of STBs in the home, even for DVR (ie. with recording).
Probably Hathway which is the market leader in Cable segment.
