There is no burden created...remembering LCN is an easy task once any individual watches a channel on daily basis. Also Airtel Digital TV provides option to create 4 different profiles for favorite channels hence one can save favourite channels of all family members under each profile.
Regarding having dedicated LCN's for favorite channels , i have already shared this feedback with senior team at Airtel Digital TV....hopefully in next few months this will be implemented alonwith channel number realignment and enabling 4 Digit LCN format.
Buddy if we start to look so closely then for each operator u will find some shortcoming or another like Tata Play subscribers complaint that having 4 Digit LCN causes inconvenience to senior citizens to press channel number remote...however on positive side having 4 Digit LCN helps DTH / Cable TV operator to arrange channels from various genre in proper manner thus having sufficient empty slots for addition of various channels and maintaining required gaps between genres on Electronic Program Guide....this immensely reduces the constant need to change LCN of channels for creating empty slots in order to launch new channels
Everything has a positive and downside, so we need to choose the best option which serves the required purpose in most effective manner
