tv_grab_uk_atlas and BBC Radio

I've installed the atlas grabber from the git mirror of the repository  
and all seems well when fetching data except for a couple of channels.  
I get from mythfilldatabase:

2014-06-05 13:56:14.736401 I  XMLTV config file is:  
/home/mythtv/.mythtv/Freeview.xmltv
2014-06-05 13:56:19.372370 E  FillData: XMLTV grabber returned error code 1
2014-06-05 13:56:19.484389 N  Unknown xmltv channel identifier:  
4fm.radio.bbc.co.uk - Skipping channel.
2014-06-05 13:56:19.512805 N  Unknown xmltv channel identifier:  
extra.4.radio.bbc.co.uk - Skipping channel.

I have an API key and it includes the PA and BBC listings sources,  
other channels are fine.

Any idea?

Cheers,
Tim.
