They can look on VUDU and see how they did with the My Lists feature to give them an idea of what to do.
VUDU has where you can create the list, give it an name based on what you put in it, and you can add what you want in the list. On Roku, they can have where you create a group for example: Filmrise and move all the Filmrise channels into the group. On the main screen, it would only show the Filmrise group not all the Filmrise channels. When clicking on the group, it will show the channels.
