Hello,would be glad if someone can clear some of my doubts,I have two SD D2H setup boxes already in my home and am now looking to add an HD box as well. Is it possible to shift my package to the Platinum HD pack now? Since i won't be having all HD boxes in house?And for the HD box will Videocon officals install a bigger dish? My old Dish was partly damaged, since i will be paying the entire 1000 for installation will they replace my old dish with the new one if the HD box doesn't require a bigger dish?
