Really? Who said that?

There *is* one poster who insists that you have to be a programmer to
compile MPlayer on Windows, but this is not true.

You need pthreads. Download it at http://sourceware.org/pthreads-win32/.
I recommend that you download the source and compile it yourself. I also 
recommend that you build the DLL version rather than the static library.

Copy the pthread headers (.h) to \MinGW\include, the import library
(lib*.a) to \MinGW\lib, and the pthread DLL to \MinGW\bin if the
pthreads build system does not do it for you.

After that, go to your MPlayer source directory and run
'make clean' (or 'make distclean' to be safe) then run 'configure' again.

Or you could not bother with pthreads, and instead 'make clean' and then
add --disable-pthreads to your configure command.

HTH.
