Mplayer plays RM file (realmedia)

Please note that to make Portable Mplayer play RM (realmedia)files it is required to put codecs downloaded from http://www.mplayerhq.hu/design7/dload.html into codecs folder....I did it but it doesn't works ....
.. this solutions do not work until you replace mplayer.exe included in PortableApps installation with a fresh mplayer.exe taken from a hard disk install.
Now my Portable Mplayer can happily play all these stuffs
