How to create an .ASX Metafile in Windows
A Windows Media .asx metafile contains a type of Extensible Markup Language (XML) scripting that can only be interpreted by Windows Media Player. The most basic metafile contains a URL to multimedia content on a server, such as a Windows Media .asf file.

<ref HREF=”http://AccountName.serverroom.us:PortNumber”/>
</Entry>
</ASX>
