Managed to find a solution to convert my 3 hour long real audio file into lots of smaller mp3 files. I originally downloaded Streambox VCR suite which enabled me to record the realaudio stream as one big file. I then used CD Wave from Etree, Etree being one of the sites that I had downloaded concerts from in the past. This enabled me to mark my split points and then save the file into smaller chunks (43 of them!). Then I used my registered copy of Musicmatch to convert from the wav file to mp3 ready to burn onto cd and listen in my Rio mp3 player. It sounds a complicated process but it was actually fairly straightforward.
