caveat: this may just be a wonky media file, or a problem in the sample code. If it's a file problem we should detect it if at all possible and report it

steps:

1. download this .mp4 video file: https://vimeo.com/31427334
2. using netbeans 7.2 create the "advanced media" sample
3. change the url in the sample to point to the downloaded file
4. build & run (or double click on .jar)

//exp: plays
//act: player launches, no audio/video and no errors. Doesn't autoplay, and clicking the play button doesn't do anything. media.status is "unknown"
