I can't turn the sequence in to yuv due to the chrominance resolution
loss relative to 24-bit RGB. We are studying very subtle artifacts in
our processing algorithms and can't be introducing additional ones.

It didn't work.

Also if there's any hope of driving the Toshiba display (4096x2160, QHD)
under Linux (which I can't currently do) I figured I had to use the
latest fglrx, esp. given the card is proprietary.  The Toshiba display
is not a standard display: It takes in two dual link DVI signals
each 1920x2160 and "stitches" them together to form the QHD image.

But this is not relevant to my current problem which is happening on
an ordinary 1920x1080 flat panel.

The machine uses a 32/64 bit Intel processor.  I don't know if that is
"AMD64 architecture" or not.

So from what you are saying, I ought to try building the 32-bit
version of mplayer (which I know works on my various 32-bit machines)
and see if that works.

I'm new to x86_64 multilib machines.  I will have to figure out what
to pull onto the machine to do this and hope that I don't create a
rat's nest for the package manager.
