Neither r33488 nor r34835 are related to any changes in DirectX code.
And what is the "Zoom function"? What exactly are you doing? What are
the steps to reproduce (command-line, key-presses, ...)?
Note that many drivers/graphics cards are unable to scale the video to
over screen size, you need to use e.g. -vo gl, -vo directx:noaccel or
-vo direct3d for that.
