Winamp should be able to do it, I found the below on their site
- Real Audio and Video (with no extra plugins)
Play Real Media format files in Winamp with no extra plug-ins. If you have Real One or Real Player already and hate it, feel free to uninstall it first, it will no longer be needed. First, install Real Alternative. Second, add the proper extensions to the DirectShow decoder:
Preferences (Ctrl-P) > Plugins > Input > Double Click "Nullsoft DirectShow Decoder..." > add ";RA;RM;RMVB" (no quotes) to the end of the extension list.
Note: this does not work for .RAM playlist files or rstp:// streams, use the Tara plugin instead (just remove ra & rm from the extension list in tara.ini).
Or just use the Tara plugin for ALL Real formats instead (recommended).
(might require you to uncheck "process audio through winamp" in Tara config).
Note: Whether you use the DShow or Tara method, you will still need to install Real Alternative (installation of Real Player is not recommended). If using the Tara plugin method to play RA & RM, then you do NOT add RA & RM to the in_dshow extension listhttp://forums.winamp.com/showthread.php?s=...did=155680#Real
