I set up my WD TV to read files on my DNS-323 NAS, dont remember how, but I did it. I recently added new files on the NAS, but my WD TV does not see them, it is even reading folders that I had deleted. I think I need to rescan the NAS, but have to idea how to do this. Also, I am confused on what I need to do for the media library. Can someone please dumb down some instructions for me?
