This code is maintained by Felix, maybe he found it non-workable or slower.
I'm busy now with putting together the stable release version.

Btw there are some more slow C code in mplayer, which should be optimized
in MMX, the OSD/SUB renderer (libvo/osd.c) and YUV scaler (libvo/fsdga.c).
Can you look at them?
For OSD renderer, I want to change character bitmaps to be 16 byte aligned
and width%8==0, so MMX code will be much easier.
