How can I stream .flv files in IIS7

I have a working solution on an IIS6, which I made using this guide: FLV 开发者_StackOverflow中文版Flash video streaming with ASP.NET 2.0, IIS and HTTP handler

The app is basically a FLV Player, but streaming is essential to it.

Now, one of our customers is running IIS7 and the streaming doesn't work, so I was hoping that someone in here would now how do handle this.

The IIS could be missing the MIME type declaration and not serving the fla files. Look at this post for a possible solution: http://flassari.is/2010/05/flv-and-f4v-files-not-found-on-iis/
