Well, the problem does not seem to be related to the video windows.
Even if you don't create the video controls, you'll have the same
problem once you've placed / received a call. I think the ActiveX
handling of NM3.01 is not very good : I created an instance of the
Netmeeting application through the OLE/COM object viewer, and was not
able to release the instance.
If you don't use other com interfaces, you can get away with a messy
CoUninitialize() right after you release the INmMgr.
Besides the video drivers should not be used by Netmeeting even when
it's idle, and when no ActiveX video window instanciated. For instance,
the audio drivers are not used when NM is idle. So we may have another
bug here.

I don't think this can be done through the INmChannelVideo interface.
Maybe other people out there have better answers.
Best regards.
