How about Mplayer? Cross-platform open source. I think the command line to make it record a stream is "mplayer [stream url] -dumpstream -dumpfile [desired file name]" Should work assuming Mplayer can play the stream at all. VLC is another good one. Open-source, cross-platform and has a great stream/converter wizard built in.

For all the good they'll do you now that you're in Spain and not giving two shits about computer stuff.
Happy whatevers to you and yours as well and thanks for the link to the game. That polar bear is awesome.
