Music Playlists Appear Under Video Menu and Vice Versa

I have created a relativee playlist with one song and placed it in a directory called Music on my WD TV Live Hub. I have also created a playlist with one video and placed it in a directory called Movies.

Now if I filter by Playlist in either the Video or Music menu, both playlists appear. However if I open the video playlist from music I get the “No media in this folder message”. The same is true of the music playlist when accessed from the Video menu. Both playlist work fine when accessed from the menu appropriate to the media type of the files in the playlist.

Is there any way to tag a playlist as containing Music or Video, etc.? Otherwise the UI will be clogged with meaningless playlists…

I think this is how it is suppose to work, the video section will only detect Videos, nothing else.
