How to play Internet Media file with live Knoppix 4.0

Thanks to Knoppix. I can boot my computer (Windows password protected) configure the IP address and browse the Internet and once done safely turn off and leave system as it is before. But when I am browsing site like BBC, I woluld like to listen it live radio, newshour (which require RealPlaye or MS media palyer) when I click suck link, it remind me no such software on system and file failed tp play.
Is there anyway I can open(play) these file with my live CD, without installing any other software
Thanks
