Downloading clips using get-iplayer --pid

I've found that certain BBC videos will only download using get-iplayer's --pid option, even with an updated cache.

The video here is one such example.

I solved the problem by going into the browser page source (Ctrl-u) and finding the pid (p01cm5hy) which then can be given to get-iplayer.

The command which works is get-iplayer --pid p01cm5hy

EDIT

Here's another BBC page which needs a different method.

In page source, find the line which begins with "writeVideoEMP" followed by a URL which you can use like this:

get-iplayer --url http://www.bbc.co.uk/iplayer/playlist/p00mbyh1
