does any know where i can i find
a free program that will make my music files(wav,mp3,wma rtc)
in to rm format

Hum, why would you want to do this ? RM is evil !

I upload like songs to listen to
converting to rm would save me MB

The only one I found was RealProducer 10 Basic
http://www.realnetworks.com/products/producer/index.html

but you can't use the files for commercial purposes
