Well. some live source directshow filters have VideoPort output pin.
and when this pin is not connected to any renderer (even if this pin
is not used for receiving video samples), video will be choppy (due to
some sync error, i think) for some cards. Due to unknown reason other
cards works fine with no renderer cnnected to VP pin.

If option is off, no renderer will be connected to VP pin (due to
capture graph building method, renderer will be connected first, but
removed later), otherwise VideoRenderer will be leaved connected to
it.
