[repeated for the other two episodes]

Going on to the BBC website reveals that the above programme IDs lead to 
pages saying 'Sorry, this episode is not currently available", for 
example ...

     https://www.bbc.co.uk/programmes/m0016jdn

... but clicking the podcast tab on that page reveals that there are 
so-called 'podcast' editions of the missing programmes available ...

     https://www.bbc.co.uk/programmes/p02pc9ny/episodes/downloads

How can I make GiP find these 'podcast' versions as well as or instead 
of the 'normal' downloads which are no longer being made available? 
(The above command-line with the --type parameter excluded or set to 
'podcast' both fail.)
