TheMovieDB Addon and UPnP

I have a raspberry pi running the latest xbmc serving content from a Drobo FS via the minidlna server (DLNA/UPnP).

I first added all my media folders (TV/Films/Documentaries) to the Video Files by navigating to the UPnP source and selecting the folder. Content plays fine from these folders.

Now I'd like to kick it up a notch. I want information about each movie and movie posters to display. I have no idea how to do this.

I'm not finding a simple how to for this task. I did find a page on how to enable TheMovieDB addon - I found it was already enabled.

But movie posters and data do not show for my movies. And the date for each movie shows 1969.

The movies are titles like this:

Dances with Wolves Extended Cut 1990.mp4

What else do I have to do to get this to work on my pi?

Thanks in advance!
