Turned off Plex Server to PS3?

Sorry I'm not sure where to put this question since it covers a couple of different areas on the forum. I have myPlex information set up to use with my Roku, which is what I want. I turned on my parents PS3 to watch Crackle (as the PS3 is in a separate room than my ROKU). I noticed that my Server is showing up on their PS3 as well. Is there a way I can turn it off so that the PS3 doesn't read it? If not, is there a way to pick and choose which files are shared/hidden so my whole library isn't shown. There are quite a few things (most actually) that they would not be interested in watching, so I'd rather not share it (if I can't get the server removed from the PS3) to make it easier if they do want to watch something. 

 

Thanks.

I'm guessing the PS3 sees the files from plex DLNA server, so you can just turn off DLNA in pms settings.

Thank you. I had tried that, I guess I had to restart PMS for it to take effect though.
