Honestly Nat Geo Music HD, TravelXP HD, Jeet HD , Baby TV HD, Times Now HD, Cartoon Network HD, Aaj Tak HD aren't that much required or have any special content which makes it worthy to watch in HD Format. SD Feed is sufficient. Nat Geo People HD is by far the most well deserving among the niche category & should be added across platforms, it airs content much better than any of mainstream infotainment or lifestyle channels.
