Recording radio highlight of Proms 2013

[general]

Hello, everyone.

The solution of "Recording Proms 2013 Highlights" (004977) works well 
for TV programs, however, the radio highlight can not be downloaded in 
the same way.

For example, I can play the program 
http://www.bbc.co.uk/programmes/p01fh7g1 with the flashplayer in my 
browser, but the program can not be downloaded by specifying PID:
     get_iplayer --type radio --pid p01fh7g1
or
     get_iplayer --pid p01fh7g1

The warning information is:
RTMPDump 2.4 git-6230845 2011-9-25

Does anyone know how to download these radio programs?

Best regards,
