I also see the behavior of scaling to the virtual size when using Xv output.  I have tracked it down 
to be due to the call mainWindow->setGeometry(player_bounds) near the end of TV::HandleStateChange. 
  This eventually ends up calling VideoOutputXv::WindowResized which causes the mentioned behavior.

It works fine for OpenGL output since the WindowResized member function hasn't been implemented.
A quick fix would be to comment out the contents of VideoOutputXv::WindowResized. That worked for me.

Another solution that seems to work, though may not be the proper one, is to set player_bounds to 
the width and height of the current screen before mainWindow->setGeometry(player_bounds) is called. 
  The attached patch does this.
