You need to search these channels by changing the frequency in system settings.
Channels will be added from 1500 onwards. You'll not be able to view any channel, blank screen will come.
If airtel adds Travel XP HD then they will talk with them too regarding this. Celebrities Management makes Music India available post paying carriage only on those platforms which voluntarily add Travel XP HD, same will happen incase of Travel XP 4K
In my opinion there is no need to add HD or 4K feed of Travel XP, this channel is now airing just old content & repeating it continuously. Also neither do we need Music India which is hardly a decent music channel, it has poor picture/audio, limited songs in library, commands neglible viewership and depends heavily on teleshopping to survive.
