Fwd: Seeking guidance to record streaming audio at time of broadcast

[Clive]

Hello,

I have not used get_iplayer to record a live broadcast. I would like to 
record Saturday's BBC R3 Opera Tosca at 6pm (in the highest quality 
available). I would be grateful if someone could give me the command 
line, with an explanation, and explain how I find the server details for 
a particular broadcast.

Many thanks.

Clive
