Noob question - content restriction

Hello, New member just signed up today and greetings to you all. I installed my new TV Live streaming yesterday. Aside from a few issues with the compiling media libray, it seems to be working Ok. It has locked up a few times but for now I will put that down to setup issues. My main concern is content restriction. I have four kids aged from 4 - 16 and would like to enforce some kind of content restriction on Videos. I have all the over 18 content in a separate folder on my NAS drive. However when adding this as a share in the Media Library Manager, this simply drops all the over 18 content into the Videos folder. I am not too concerned about that as such, but I would like to add some form of password protection in the WD so that this content is not viewable without a password. This is something that is built into all high end media servers like Kalidescape. Does anyone know if this is possible on the WD TV Live? Many thanks Slip
