Hi,
There are several software which convert .rm to .mp3. One of them is
"switch", this is free software and available on internet. You
download it and convert the format.
Thanks,
Ritesh
Which part of the commandline you don't understand?
mplayer -ao pcm:waveheader input.rm | lame -b 16 -m m - output.mp3
man mplayer and lame

Try mplayer or ffmpeg commandline to convert.
For GUI app search for convert here : http://kde-apps.org and
http://www.gnomefiles.org/search.php?search=convert you will get tons
of them.
Have fun
