Newly created "root" folder can't be found from WD TV Live

Hi all, I’ve got a white My Book World Edition (white light), on which I’ve created a third folder besides the already existing Downloads and Public. I’ve given full access to that folder to the Admin user, the same user I’m using on my WD TV to access the network share, but yet I only see the two originally created folders. I also tried adding the folder to the Twonky Media Server, but I can’t get to it there either. This very much sounds like something to do with permissions, but I can’t see what it is?! Do folders need to be public in order for devices like WD TV to discover them? Thanks, André

answering my own question: setting folder to public worked. not ideal, but I guess best I can do right now.
