Windows Media Format 9/10/11 SDK (Windows) 
http://msdn.microsoft.com/en-us/library/aa387410(v=vs.85).aspx

This isn't required for the direct show backend to operate.  However we check 
if it exists because it includes some API which can be used to get meta-data 
from windows media formats which otherwise wouldn't be accessible.

Windows Media Player SDK
http://msdn.microsoft.com/en-us/library/dd758070%28v=vs.85%29.aspx

This is for an alternative windows backend (actually the original windows 
backend) and isn't needed for the direct show backend.  That backend is 
actually disabled by default so the configure test is more informative than 
anything.

Microsoft Media Foundation.

This enables using the Enhanced Video Renderer from Media Foundation for video 
rendering in the windows media player backend, instead of ActiveX embedding.

This is what the WindowsMediaSDK refers to.

Media Foundation was introduced in Windows Vista and there are only a few API's 
(EVR is one) that are available under limited circumstances in Windows XP.
