Yes media companion allows you to pull posters and art from all the sources imdb, tmdb, fanart.tv ect does it all automatically but can easily change with a push of a button even pick resolution case you want higher quality or save some space. and that's for all you art to, I don't know if your skin uses it but all the clear art ,logos , thumbs, banners ect . ect.. and yes it pulls all the actors names and thumbs, tag lines , plot , ratings from all the critics and everything else.. it's a little overwhelming with all it can do at first but it's straight forward and easy to work with .. will do tv of course also and music videos and home movies .. I'm not trying to push you on anything but It free after all but it would take me hours to go over everything it does .. ( even does file renaming if you want) don't think you can go wrong with it .. but like I said it can be overwhelming with all the features....
