I seem to remember seeing markings in On2's source code for Duck TM1
that implied that it compiled for the PS1. I don't know if any PS1 games
actually used it.

I don't personally know of any PS1 games that used non-MDEC video. But I
have not studied them extensively.

No clue. It just landed on our samples FTP a long time ago. Maybe it's a
genuine candidate for removal? I suppose that due diligence would entail
finding other PS1/MDEC playback utilities and seeing if they can handle
the file.
