Polimer cable is called as VK Digital and we are currently discussing the same in the following thread, Link Removed
As far as analogue is concerned, i see that VK gives 2 sports channels and much fewer English and Tamil channels. So those who are pure sports fan and don't care the rest would find VK useful.
But those who want English and Tamil channels in more numbers and don't care about sports would find SCV beneficial.
Which area are you from? Will your LCO replace STB free of cost or offer any discount for the same?
