How do I get my skin to show the extra fanart? The add-on doesn't download anything I noticed, so how do I get it to download the extra art and let it show them?

1) Nobody can answer your question cause you not mentioned wich skin are using.
2) With "extra fanart" you probably mean the extrafanart folder in your movie folder with .jpg's in it wich most skins are working.

That's not an artwork type called via List.Item, ArtworkBeef don't handle this. Media Managers for example can do.
