I think he'd like to see the actual cover and not a thumbnail taken from the stream.
This plugin would do the trick viewtopic.php?f=2&t=2126&start=300&hilit=imdb
Or you can add a picture called <moviename>.cover.jpg (<-- don't know which extensions are supported) into the same folder as your movie file. E.g. 'Big Buck Bunny.avi' would display a picture Big Buck Bunny.avi.cover.jpg
