I get that message too, but it works, so I don't think that it is the cause of
your problem either.
My software:
gcc 3.4.5 (MinGW)
binutils 2.16.91
MPlayer svn 25096
fontconfig 2.4.2
freetype2 2.3.4

Try a different vo (gl2 or gl).

Also, you mentioned that mplayer's configure had problems detecting fonctconfig
and freetype. Do you remember what you did to fix the problems? I had a recent
problem, but I only had to edit the test for fontconfig in the configure script.
I did not have to do anything special to compile fontconfig or freetype.
