Actually Marc I can already fix the MP3 files, as I wrote in my post, by 
re-encoding each MP3 file with Lame.

I'm just wondering why this is happening with every single radio 
download I make (that's converted to MP3 by get_iplayer which I 
require). Clearly something is not working properly but I don't know what.

Thanks.
