Pulling movies from network share - WD TV won't refresh the list

I re-organized the movies on my Win7 PC. 

I have a network share setup in my media library, which I made into a favorite (not sure I have all the terminology right).

I’ve tried rebooting the WD box, and looking for a refresh option in the ‘options’ menus, but I still can’t get it to update the list of movies to reflect the changes I made.

Any  suggestions?

are you using the Media Library? if so go to settings->setup->media library->media library manager for network shares then rescan the shares you made changes in.
