Its the autoplace that puts the vic windows on the G400/AGP
cards.  

	* You press the "autoplace" button on your VIC while it is
running.  This will pop up a frame with wireframe images of
your monitor layout.  

	* Click with the right mouse button to drag out the area
that autoplace should place video windows when you enter a
virtual venue.  
	
	* Select the checkbox that says "autoplace activated"

	* Press "apply" to activate the changes

	* Press "write vic prefs" to make the changes permanent

Then each time you enter a new venue, the new vic windows
will pop up on the displays driven by your AGP card.  These
seem to be able to handle the video much better than the
G200.
