Works great, we don't use it much at the moment since there isn't a
well-integrated solution in place for the JPEG capture side in the AG. It
can use DirectDraw overlay planes for hardware color conversion and window
resizing.

With a single window we see lossless decode at 30fps. It consumes most of a
CPU tho. We've had someone investigating 640x480 decoding, hacking the
deinterlacing by decoding into alternating lines. (Anyone have a better
solution implemented?)
