It is because some movies they telecast on channel they have rights to only on satellite television that is tv channel for such movie they don't have digital rights telecast rights. If they want to telecast live movie channel then they have to aquire all the movies satellite as well as digital rights of all those movies untill they won't telecast live movie channel on hotstar (In now days it is impossible to aquire every movie satellite as well as digital rights because of taugh compitition) so they did not telecast live movie channel on hotstar.
