Seagate Personal Cloud and Plex Media Server question.

Hi. I'm wondering if someone could help me out. I installed Plex Media Server onto my Seagate Personal Cloud (It had the app in the apps for it) I can access the Plex Media Server from my laptop using the IP address of my Personal Cloud and I can see all the movies are loaded and I can even play them from there -but when I try to access Plex from my TV though smartshare thing all i get is an icon with DNLA but there's nothing in the video, music or photos file. The usual Plex icon is not there. I'm pretty much at my wits end with this so any help would be greatly appreciated.
