Shared Videos folder, can't see contents... (Mac OS X)

When I’m looking at my WD My Book Live folder info for Shared Videos, it has:

daapd:   Read & Write

staff:  Read & Write

everyone:  Custom

It won’t let me see the contents of the folder, nor will it let me change the Privilege for “everyone”.  Other folders, such as Shared Music has Read & Write for Everyone Privilege.   I try to change is, and it says I don’t have permission.  

I can see the movies on my iPad and iPhone, but not via my laptop in Finder. 

Hello,

Make sure that you are login in with the administrator user.

I am. It won’t let either of my user accounts see the contents of that folder.
