title: Enumerating and using wmp visualizers
body: <p>I want to use the systems available windows media player visualizers in my app. Apperently visualizers expose an <a href="http://msdn.microsoft.com/en-us/library/dd563253%28v=VS.85%29.aspx" rel="nofollow noreferrer">IWMPEffects</a> interface to the world. My question is how do I enumerate and create instances to the available visualizers on my system? Probably it's just a process of getting the cslid of the visualizers and then create the instance with CoCreateInstance. However I have no idea how to get these clsid's!</p>
  
  <p>Thanks!</p>
