can I get help playing Realplayer streams?

Hi guys & gals I hope you can help. I love listening to BBC radio and would really like to make more use of it's "listen again" feature http://www.bbc.co.uk/radio/aod/index.shtml However, I cannot seem to get the buffer to refill beyond the first 4 or 5 minutes. This happens whether I use either Kaffeine or RealPlayer or play the stream. In addition I am finding that my Konqueror will not play ball at all at this URL but consistently crashes. Is this something any of you have come across before? or should I raise a bug report with the KDE developers? Thanks for your time and interest Regards, Sylvanus
