My WD TV Live showing too many folders from my REadyNas

Hi guys!, I have a Netgear ReadyNas NV+ V2 and a WD Live TV hooked onto a Fritz Box and the problem that I have is that when I go to the VIDEO tab on the WD tv live it shows too many folders instead of the just one “video” folder.
At the same time if I go to Windows under “Devices and Printer” and onto the ReadyNas media server I can see also the same folder structure that I see on the WD.
My question is how can I see only a video folder under the VIDEO tab and a music folder under the MUSIC tab and so on because now there are too many folders under those tabs.
Thank you so much in advance for any help provided.
