A wrapper playlist can contain references to media files that are streamed before and after the content requested by the client. Hence, the media files wrap the requested content. You can use a wrapper playlist to guarantee that every client connected to a publishing point renders specific content. In the following wrapper playlist example, media content is inserted before and after the requested content that is indicated by the "%url%" placeholder:
<seq>
<media src = "c:\wmpub\wmroot\content1.wmv"
<media src = "%url%"
<media src = "c:\wmpub\wmroot\content2.wmv"
</seq>
