Select MENU>> TV CHANNEL>> TV CHANNEL EDITOR
Press F1 to alternate between showing the full satellite list and just a FAV group (in your case show all satellite list)
Now find the channel that you want to add or remove (you will see heart icon next to a channel that is already in a FAV group) and highlight it.
With the channel highlighted by the yellow bar, press FAV
Now you will see a row of icons (16) for each FAV group, eg. music note, shopping, etc.
Simply select or deselect any of these icons to add or remove a channel from its corresponding FAV group. Each icon is a FAV group, ie. 1 to 16.
When finished, press EXIT and SAVE.
