Manually overriding metadata?

I have a few domestic (Sweden) movies that are not in TheMoviedB so I've created custom XML files an images for them as per http://support.firecore.com/entries/20557283-Metadata-and-Cover-Art.

Everything is fine except in the library they show up in the "Other" section rather than with the preferred "Movie" section, what am I doing wrong?

The XML starts with <media type="Movie"> and that should do it, or?
