MP GUI uses DirectX/Direct3D (like I said earlier). Windows Forms use GDI. Those two don't mix well. In fact they don't mix at all in full screen (DirectX exclusive mode). These are entirely different technologies not designed to work together (with the exception of windowed DX which work more or less like an overlay). MS recommendation when you want to display a window on top of fullscreen DX surface, used to be after each WM_PAINT to grab BitmapBits from window DC, turn that into a texture and the use DX to draw that texture on top of fullscreen DX surface. I do not know if there has been some enhancement in later DX to allow for a better solution, but I doubt it.Needless to say this technique is VERY slow and should only be use to show e.g. a message window, or a window with some options etc.That being said, you might want to have a look at (in addition to onlinevideos which probably does exactly what you want to do) winamp visualizations. Also external players implement similar functionality.
