I have made the test for the shader capacity in the constructor for Direct3D9Presenter in order to avoid failing when the filter becomes active (since it's too late to fall back on DirectDraw).
I've add a call to
_form_LocationSizeChanged(this, null);
after adding the event handler in the constructor for DirectDraw7Presenter in order to have the _rect member initialise in all situations (I had to move the window to get the video to display).
Not sure if it's necessary, but I add calls to the base method in the override of the VideoControl class when Repaint is null (I tried that when debugging the previous problem).
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
