This guide is good, and there’s even a link to a page with instructions on doing the same and more on Linux!
And in a timely coincidence, Justin’s delicious bookmarks points at this page with instructions on recording streaming audio with Mplayer! I’ve done the same and posted command lines here before. Go search for “mplayer” or something! Lots more Linux stuff on that site including the odd opinionated piece..

I recently wrote a guide explaining how to convert .ra files to mp3 using mplayer and lame on cygwin. I should work the same on windows. You can find it here : http://www.digital-atheist.com/tutorials.html

Try this, I was able to do this today and it works great. I’m listening on my Ipod right now.
