Python win32com doesn't know module name

Question

I was looking for the python Zune (Windows media tool) api when I looked at the COM browser in pythonwin. I found something called ZuneWmdu Type Library (1.0). I used makepy in this lib, it generated a file

9FE20C05-81CE-46D7-9C56-FD97A865BBB8x0x1x0.py 

in

 python 2.7.3\Lib\site-packages\win32com\gen_py 

I do not know what to transfer to

  win32com.client.gencache.EnsureDispatch('???') 

I tried to call

 win32com.client.gencache.EnsureDispatch('9FE20C0581CE46D79C56FD97A865BBB8') 

The result in the exception (pywintypes.com_error)

(the x0x1x0 part of the .py file seemed unbound)

I tried the same with

 win32com.client.gencache.GetModuleForCLSID('9FE20C05-81CE-46D7-9C56-FD97A865BBB8') and win32com.client.gencache.GetModuleForProgID('9FE20C0581CE46D79C56FD97A865BBB8') 

Both return None. I'm stuck here, I need to either find what is called a library (for itunes, you would call:

 win32com.client.gencache.EnsureDispatch('iTunes Application') 

for example) or how to call a module with a GUID

Or even someone tell me that I'm doing something completely wrong.
