Network Shares & Media Categories

I recently bought a WD Live SMP and have been quite pleased for the most part.  One small issue I have is that all the network/media shares are showing up for each media type.  Each media type (ie.  pics, music, video) is stored in a separate directory, however when I go to videos it shows all attached network/media shares (music, pics, videos, et al).  How do you set this up so only the relevant network/media shares are available for each category?
