not same as mag receiver, otherwise it would be a version of Stalker middleware and not a Smart app being used.
But to answer queastion, you could try a playlist m3u file... if your Smart TV app will play the m3u format.
If so, then take the m3u file (the playlist) and open it on your desktop with notepad, and delete the adult channels ... that will delete them completely. You can save them onto a separate Playlist m3u file thou, if wanted.
Look at VLC forum section sticky thread for more info concerning arranging m3u playlists.
