well dear members wait a little more when st2 satellite bcomes operational,tata sky will share and get hd channels from d2h, so one tp will b vacated and new sd channels will b added along with new hd channels. and the big news of major additions will happen in april 2012 once gsat10 bcomes operational at same orbit 83 degree east. well in future too tp sharing will continue between d2h and tata sky as it will save costs and both companies wil b able to give max channels on combined transponders. one or two transponders will b kept by each for diffrentiation
