Serviio

Serviio is installed on my PC and runs on my Xbox 360. I have a 1 Tb external HDD attached to the PC which holds all of my video files and everything runs, for the most part, fine. I have all of my videos categorized on the HDD (All action in a file, all Drama in a file, etc) and added each genre file individually to serviio library. I have added new videos to my "TV Shows" file and now that file, on the Xbox, shows 'no videos found'.
I have removed the entire file and re-added it and nothing changes. Force refresh does not work.
Thank you.
