<p>Currently the MovieMDE only uses an Imdb-ID, if present, to uniquely identify a movie on TheMovieDb.com, before trying to get a unique match based on title and year of the movie.</p>

<p>The NfoMovieMDE, however, extracts Tmdb-IDs as well, which could be used for unique identification on TheMovieDb.com. Same goes for the MatroskaMatcher.</p>
