You can also render your web page over the xvideo window. The xvideo window is a solid colour (often a bright blue or green), and any pixel in that colour gets video instead of the pixel. So if you draw on the window you will see it. No blending though, it's an either-or sort of pixel thing. That's why if you overlay a window on top of your video output, and it happens to have pixels of the magic colour, the video shows through. So if you take your web browser, and set its background to the magic colour, it should provide a (not particularly pretty) overlay on the video.
