Currently there is a way over streaming the file.

First of all, we need a place where it should be always possible

        string streamPath = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) + @"\";

Next Step an Instance of the MediaPlayer

    WindowsMediaPlayer wmp = new WindowsMediaPlayer();

Then we need to stream the Assembly Resource

    Stream stream = Assembly.GetExecutingAssembly().GetManifestResourceStream("Smartis.Resources.Natur.wmv");

    using (Stream output = new FileStream (streamPath + "mediafile.avi", FileMode.Create))
    {
        byte[] buffer = new byte[32*1024];
        int read;

        while ( (read= stream.Read(buffer, 0, buffer.Length)) > 0)
        {
            output.Write(buffer, 0, read);
        }
    }

Finally we should be able to load the file.

    wmp.URL = streamPath + "mediafile.avi";
    wmp.controls.play();

---

After playing don't forget to clear the folder:

    File.Delete(streamPath + "mediafile.avi");
