Sonarr creates NFO files like this:
<tvshow>
<title>Dark Angel</title>
<rating>8.4</rating>
<plot>[...snip...]</plot>
<episodeguide>
<url>http://www.thetvdb.com/api/1D62F2F90030C444/series/76148/all/en.zip</url>
</episodeguide>
<episodeguideurl>http://www.thetvdb.com/api/1D62F2F90030C444/series/76148/all/en.zip</episodeguideurl>
<mpaa>TV-14</mpaa>
<id>76148</id>
<genre>Action</genre>
However, some features require a little bit more info (as described on the Kodi Wiki), such as the Lite IMDB Ratings Update addon. In this instance, it’s looking for one of these two additional lines:
<id>76148</id>
<uniqueid type="imdb">tt0204993</uniqueid>**
<uniqueid type="tvdb" default="true">76148</uniqueid>**
Any chance of getting a little bit more into the NFO file Sonarr creates?
As an aside, Radarr would need a line like this:
<id>tt123456</id>
<uniqueid type="tmdb">567890</uniqueid>
