Yes, that is all I needed.

these nfo files have the respective IMDB ids in them

Not the one you provided above. There is no IMDB id in them. And the use of ID's in the nfo file is incorrect.

This is correct implementation of ID's for Kodi. You will need to bring this to the attention of the developer of the media manager.

xml:
    <uniqueid type="imdb" default="true">tt0405422</uniqueid>

    <uniqueid type="tmdb">6957</uniqueid>
