Thanks to stupid "Real" (that I hate also by the way), there is no straight forward way as they try to keep their technology very private ... that's why they suck and no one cares about them anymore. However, there is an easy solution to your problem. Set your audiocard mixer to record from the WAV output. Using the standard windows mixer, you can go to options, properties, and in there you can pick recording source. Then set volume levels to about 50% ... play your RM file while recording using windows recorder into a WAV file. Convert wav file to mp3
