<p>What I mentioned is that this build of the codec (done in November/02) does
not contain changes/bug fixes/optimizations that can be incorporated into
the cvs tree, according to the original Japanese developer. Hope this is

<p>My experience shows that a lot of time is spent writing pixels to the
screen, not decompressing the frames, so video drivers really make a
