Unfortunately due to the overhead of the X Window System, it may
never be as fast as Windows' ability to go direct to the hardware
through as few layers as possible.
Maybe with X running on top of the framebuffer interface, there
would be a way to get direct access to the framebuffer API for the
window area being used, so that the frames could be blitted to
it at a faster rate.
Then again, xawtv does surprisingly well... I think they found a way
to get direct access to a block of video memory, or something like that.
As for optimizing xanim to the extent possible, a big one that I
noticed is that by default, it tries to load the entire movie into memory
before playing it, which will take a long time and cause a lot of swapping.
The flag to play directly from disk makes a big difference. I don't know
why that isn't the default setting because it usually works better.
