When it comes to media players on web sites, it is generally considered bad form to start auto start. When you have a media player that does auto-start it inflates the download counts. For both of these reasons our players do not and will not support auto-start..
Imagine a show on a advertising deal having auto-start implemented and the page got 5000 page views a day that would result in 5000 false download counts. There are other players available that you can implement that will do an auto-start but none that I know of that will loop a downloadable media file.
