DRI2 creates off-screen buffers for all drawing, so if the window is
within the DRI size, it should work fine. The buffer swap is done using
the 2D engine, which can handle larger objects.

Yup.

Nope. There's no extra buffer here (unless you use the Composite
extension), and so the 3D unit won't be able to paint the video on the
screen.
