You mean the RealAudio stuff? There's no plugin I know of. A bloat free option is mplayer. Good frontend+binaries: http://mplayer.de.gg/

You can also use Real Alternative. http://www.free-codecs.com/download/Real_Alternative.htm

I haven't tried it but haali dshow wrapper and real dll (or alternative or the original) and Real Media Splitter (http://sourceforge.net/project/showfiles.php?group_id=205650&package_id=246121) might do it for you.

First off thanks every one who they are reply me.
And by the way,It's rtsp format include that which run by notepad.exe
Just like that:

rtsp://rmlive-lr.bbc.co.uk/bbc-rbs/rmlive-lr/ev7/live24/london/live/bbcldn_fm_g2.ra?BBC-UID=74b7ad75e70c12a7b923edcc50c0abbffc6c408e70c051b4a4ef0821fcfa3ced&SSO2-UID=

I really want listening bbc london radio(above),so give me hands again,brothaz(plz~)

The way I told you works (tested!). Install the mplayer mentioned above. Start the smplayer gui. File-Open-Url, your URL works.

My k-lite codec pack can do that,too.
