I am new to DTH so I have a few questions ehich I hope someone can answer:1) I plan to go with the basic Dhamal pack for now but I may upgrade to the HD pack later. So how will the STB change take place? I mean will they come to my place and change it? and if I decide to cancel HD, will someone come to take it back?2) Is TATA SKY reliable?3) What about the Rainy season? I have heard there is a lot of problems in the rainy season. Care to elaborate?4) Whats the price for HD STB? I checked the on the TATA SKY site but I came across a few offers not the price of just the box.P.S.: Please note I am talking about the Tata Sky HD only. I do not need the recording function.Thank you for reading through!
