The recorded shows you can simply download
http://devel.autopod.ca/chum/9/podcasts/
The live stream seams to be at
mms://a1881.l7935335880.c79353.g.lm.akamaistream.net/D/1881/79353/v0001/reflector:35880
But it's down at the moment.
Code:
mplayer mms://a1881.l7935335880.c79353.g.lm.akamaistream.net/D/1881/79353/v0001/reflector:35880 -dumpstream -dumpfile out.wmv
Will dump the stream
You can also use mencoder to just get the audio.
You can also use ffmpeg to capture the output of your sound card.
Code:
ffmpeg -f oss -i /dev/dsp0.0 -vn -acodec libmp3lame -ab 128k capture.mp3
That was for oss, if you use alsa then use your own parameters.
