I would first check if video capture extension works anyway.
I couldn't get it working, ...
... it seems to start ok
... but moving the captured window,
... or sometimes even just moving the mouse hangs the program :-(

So I'm still looking for a good / open source workiing video capture in 
Python.
I can make a good working capture in delphi,
make a DLL or ActiveX from that and use it in Python,
but I'm not allowed to ditribute these.

cheers,
Stef
