Recording Quicktime RTSP Audio Streams pm a Mac

[any ANONYMOUS forum user]

My favorite band does live web broadcasts from time to time and it turns out I've missed four of them. Lucky for me they have them archived on their site and I can stream them to listen to them.

Unlucky for me I don't have the time to listen to them streamed and I want to record them so I can put them on my iPod. But I have no clue how to record a Quicktime audio stream-- no video.

I was told it's possible with VLC but I tried three times yesterday and didn't get anything except an unplayable file. Anyone know how to do this with VLC? Or any other program?

Also, how do I get the RTSP links to Quicktime audio streams on a Mac? I can do it in Windows, just not on my Mac.
