Windows Media Format SDK using UPnP to map ports?   

We have a video application that uses the Windows Media Format SDK that uses 
a WMWriter instance configured with a pull sink.  Clients connect to the pull 
sink and can receive video.

However, one thing we're noticing is if our clients have UPnP enabled 
routers, they see an entry in their router that looks like "Windows Media 
Format SDK (application name)" where app name is the name of the hosting 
application.  For example, if the app is called vid.exe, the entry on the 
router looks like "Windows Media Format SDK (vid)".

This is interfering with our own attempts to use UPnP to map ports on the 
user's router, and the format sdk doesn't seem to have any documentation on 
how it performs this, how reliable it is, etc.  

Any info is much appreciated; I've scoured the internet and found a few 
people having similar issues, but no explanations or answers.

Thanks in advance,
Jeremy
