3.What I have done.
My system is amd64.There is no win32codes,but there is essential-amd64.The readme in it said I can put them to /usr/lib/codecs or /usr/lib/win32.
I do,but the mplayer still can not find.
So if I know the path where mplayer to find,I can put essential to there to try.

These are what I can provide.Please help me.
