Series/Episode categorization with the RDP-To-Scenegraph example

Thank you for taken the time to share your codes and structure, Nice job1 i my self like what you done and want to mtry and see if I can make something like this with one of my channels that uses a tvspecials category but pull episodes from playlist. I can only get one line of videos like most here and trying to figure how to pull the playlist categories. I want to try your method and see if this can work without having to change the whole json feed!
