It's slightly different for get_iplayer.  For one thing, the bit rates 
listed in the streams' metadata from the BBC don't necessarily 
correspond to what you receive.  Radio 4, Radio 4 Extra and national 
music stations list 128k and 32k, but you get 128k and 48k.  The 
exception is Radio 3 which also also offers a 320k live stream, but no 
320k catch-up afaik.  Radio 5 Live lists 128k and 32k, but you get 96k 
and 32k.  Regional radio lists 128k, and you get 128k.  Local radio 
lists 128k, but you get 96k live and 80k catch-up.  Just to round things 
off, BBC World Service lists 32k, but you get 64k.  There are no doubt 
some exceptions, but this seems to be gist of what's available.
