how can I burn rm files?

Hi

I have RM Recorder v 10.2 which I use to record real media audio files from the Internet. I have tried to burn the rm files to cd using Nero 6 but I get an error message saying:

'one or more files cannot be added to the compilation. It may be possible that the files can be added if a dedicated plugn-in is installed.'

Does anyone know what plug-in I would need and where I can get it from? Or is there another way to burn these files to cd?

Thanks
