Downloading Italian language video "La mappa misteriosa"

[Steve Goodall]

Can anybody tell me if it is possible to use get_iplayer to retrieve
the video from this (and similar) pages:

http://www.bbc.co.uk/languages/italian/lamappa/episode/1

Trying to watch the video through the web page is just about
impossible - you get a few seconds at a time and then it pauses for a
minute or several.  I realise the page is archived, which probably
explains the poor response.

I would normally download using the GiP command line, using PID, but
can't find a PID or any clues to it.

Any suggestions gratefully received.
