If you have a movie in a folder with the movie name (think movie and Featurettes folder in this folder) when you view that movie in the library on the preplayback screen at the bottom where it shows the actual file name it only shows the folder name.
If you go to that favorite and navigate to that same movie in the folder it shows the actual file name, not just the folder name.
Would be nice to see the file name in the library too.
