Missing Video Content?

I Run a Samsung UA55ES7100 smart TV and got sick of adding movies into my library but it being luck of the draw as to when Allshare will refresh and let me view them, so I just downloaded Serviio this morning. All my videos are on the one hard drive, grouped into several main folders for Movies, TV shows my sons movies... etc.
When I go into Serviio on the TV the folders are all visible in the "Folders" folder but the content is missing from a few folders. Do I need to just have all the movies, TV shows etc just in one folder and let serviio sort it out? Or is there something I need to do to get these other folders to recognise their content? Im new to this so any help would be greatly appreciated. Thanks.
