^^ I don't think Analogue having bandwidth problem. But Quality problem.
The main concern about Zing is that one who moved to Zing will miss Local Tamil channels. Another main concern of Zing is that many Tamil channels are missing. Few criticizing Zing because its not a Tamil centric DTH but offering as a Tamil DTH they want everything in Tamil that too in Rs. 100 or less then that. Peoples want more offering in Tamil which Zing will fail to fulfil. It will never succeed in my approximation because peoples are happy with Analogue cable and I am quite sure TM will remain analogue after decade also.
