If they really pay 20kEuro, kostya shall get some of it and rewrite this file
iam no going to spend more time with searching the authors of
Olie Lho is the original author but there may be commits from other people
like walken on top of this and walken is very picky about licenses.
also the file was moved around in mplayer wiping out history once and
there was at least one sync with mplayer xp.
that means i would have to go over libmpeg2, mplayer, mplayer xp and possible
some other repos ...

This one simply is not worth the work, rewriting is less work, especially
considering that we cant find the main author and considering that it was
attempted in the past already to find him unsuccessfully. I dont belive
if diego failed i would have more success
