An example is this site using Xfilesharing pro as well:
http://rockdizfile.com/4efq22tbnltc
The source provides this in the header:
<meta property="og:video" content="http://rockdizfile.com/mediaplayer.swf?file=http://rockdizfile.com/mp3embed-4efq22tbnltc.mp3" />
http://rockdizfile.com/mp3embed-4efq22tbnltc.mp3
This downloads straight away whereas the default setup for Xfilesharing pro is to show a player and play the file.
Thanks!
