Try starting up the player itself and see if it will play those files. Something else may be the default player for those file types, like Xine or Mplayer.
And try "export PATH=$PATH : path/to/RealPlayer-10.0.1/realplay" then log out of the windows environment and back in. (remember no spaces in the export command)
