Bob,

The Eastman House frames aren't all I have. I recently got some frames from 
the Library of Congress. Those are mono DPX. Will put some up at Digital 
Film Library when I get time.

That may be impossible. What I can do is ask that artists who worked on 
those movies create some test frames without any copyrighted content.

You may want to look at how CinePaint handles it. We cheat, use a bit shift 
instead of a gamma-correct table lookup. Bit-shift is very fast and doesn't 
have round-trip rounding errors.
