I have also run into some realaudio links that I cannot figure out how to 
extract URLs from, such as the one at WCPE.

http://play.rbn.com/?url=wcpe/wcpeint/g2demand/prerollad.rm&proto=rtsp?wcpe/wcpeint/live/liv_28_56_rm

I have no idea what to extract here.

It is not the part before the first ?, I just got 0 bytes and exited at 
end of file.  http://wcpe/wcpeint/gsdemand/prerollad.rm did not work 
either.  Realaudio is not very transparent.

For purposes of comparison, I played 
http://audio.ibiblio.org:8010/wcpe.ogg  (ogg)
and http://audio.ibiblio.org:8000/wcpe (mp3)

Both say you need at least a cable modem.

The MP3 file played until it ran out of buffer (rather soon, since it it 
224 kbit/sec and my connection is about 44kbit/sec of that) and then 
terminated with premature EOF.

The ogg file kept playing, with an occasional little skip and with good 
quality sound, until I went online to write email, then it stopped getting 
the signal fast enough to keep up and also terminated with EOF.

They both seem to be 44100Hz sample rate, 16-bit stereo.  Is the ogg also 
averaging 224 kbit/sec?

I think the ogg file filled the cache a bit sooner but I did not time it.

This is the only classical OGG station I have listened to so far (I still 
can't find my way around CBC and will need to look it up in an email).
