Question about meta information for movies

I have my movies in individual folders by themselves. When I look at the top level folder, I see the thumbnail for each of the movies, but the information for them (like length, genre, release date etc) is all N/A. When I go into the folder, the information is fine and everything shows up correctly. Any ideas on what I am doing wrong?

Should the movies all be in one folder or is it OK to have them in individual folders by themselves (like I have) and still have the information show up correctly?



The info for each movie is placed by WD in the same folder as the file, so to have the movie info show as you peruse the thumbnails all the movies would have to be in the same folder, rather than individual folders. At least as far as I know.
