TV Show Not in Library

Show won’t show up in library automatically, so I’ve attempted placing a tvshow.nfo file in the tvshow directory, but I still get nothing.

The show is Beowulf: Return to the Shieldlands

Directory:
TV SHOW – To Watch/Beowulf: Return to the Shieldlands/

tvshow.nfo

PHP Code:
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<tvshow>
    <title>Beowulf: Return to the Shieldlands</title>
    <showtitle>Beowulf: Return to the Shieldlands</showtitle>
    <episodeguide>
      <url>http://thetvdb.com/?tab=series&id=301347</url>
    </episodeguide>
    <episodeguideurl>http://thetvdb.com/?tab=series&id=301347</episodeguideurl>
    <id>301347</id>
</tvshow> 

When I click ‘update library’, nothing changes. The show does not show up in the library list of shows. It has a thetvdb.com entry, so why isn’t the scraper capturing this show?
