I've been trying to figure out how to record streaming audio so I can listen to it later (and start/stop when I like). Actually it's specifically for [The Hitchhiker's Guide to the Galaxy Quandary Phase](http://www.bbc.co.uk/radio4/hitchhikers/). I didn't really enjoy the last radio series and the repeats of the TV series aren't that great either. But it became a technical challenge that I wanted to get to the bottom of. I finally cracked it today. Note that the solution below will not work behind some corporate firewalls but seems to work fine on my NATed setup on a Linksys Wireless Router at home.
Download MPlayer for Windows and all the codecs.
Unzip MPlayer and unzip the codecs.Copy the unzipped codecs to the codecs sub-dir of the mplayer dir.
Open a command prompt in the Mplayer dir and type:
mplayer -dumpfile hitchhikers.ra -dumpstream rtsp://rmv8.bbc.net.uk/radio4/hitchhikers/hitchhikers.ra
It streams in realtime so it'll take 30 mins to download.
Listen to ram file later at your leisure using realplayer (or the nifty stripped down, bloat-free [Real Alternative](http://www.codecguide.com/about_real.htm))
Do that once a week to get each new episode.
Don't try this with VLC. I spent ages trying to get it to work before I realised it doesn't support realaudio!
