Tata Play can easily add And Xplor, Colors Cineplex Bollywood , Colors Cineplex Superhits, Investigation Discovery HD by updating RIO with respective broadcasters. I do not see addition of these chs interfering with RIO terms of other broadcasters or even if it does some LCN changes can b made like airtel shifted Colors Cineplex HDMI towards end LCN to accommodate Colors Cineplex Bollywood, i think they can do so with MTV , MTV Beats too by shifting it towards some latter LCN and add their HD feed alongwith VH1 HD but i am sure viacom18 will not agree to it as these r their key channels.
Earlier on too broadcasters must have approached Tata Play (Tata Sky) to add these channels thru carriage fee option as same were not available in RIO but Tata Play seems to have decided not to add them. I still feel Tata Play is somewhat partial to star/disney channels bcoz they r partners in their company whereas airtel does not have that tilt towards any particular broadcaster
