Forgot to mention last night, the frequencies of new H transponders is in range which r not functional/existing in V polarity of GSat 10. Quite sure that these new transponders r from GSat 10 and difference has been maintained to avoid interference during reception at subscriber end.
Also channels rearrangement and additions will happen post this, first they need to be sure that transmission is stabilised then only broadcasters can be informed about making necessary changes. There will always be friction among broadcasters to get best slots but finally its upto Tata Sky to decide allotment. This is not a big concern and will be taken care of in a timely basis
GSat 31 will also open doors for acquiring new transponders as shortly they will require it. &Xplor HD addition being kept on hold may also be bcoz they want to reserve bandwidth incase delays happen later on for new transponders.
Lastly after they have decided to drop VOD service, guess next step would be migrating to HEVC for HD transmission. Possible that new hybrid box will have external recording feature alongwith OTT so as to give existing DVR subscribers chance to shift towards an advanced gadget by giving attractive offers.
