This may be a dumb question, but as I haven't seen the codecs on the freshrpms - did you download them from mplayer.hu?
Yes -- I dl'd the first file (named All-in-one end-user package (DMO,Indeo,QT,Real,3ivX))on this page:
http://www.mplayerhq.hu/MPlayer/releases/codecs/
I then extracted this to /usr/local/lib/codecs (which was a directory that I did not find initially, so I created it).
then I ran ./configure, make as described earlier.
