fixed: Some movie filenames were treated as tvshows causing lookup failure

Many movie filenames use schemes like "Movie.(year).[x264-GROUP].ext" which were previously treated as tvshow obviously causing lookup to fail. This workaround fixes that. Note that I've also tested it with some of my tvshow/episode files, and it still seems to work for those too (although the orginal hack is still rather nasty -> perhaps we need some API function to pass the content type?)
