Request assistance in downloading multiple programs with one command

[roadcone]

I routinely use the command line on Linux and am comfortable d/l singles or series using partial matches. I would like to d/l hundreds of shows from the World Service's Witness series:

http://www.bbc.co.uk/programmes/p004t1hd/episodes/player

but don't want to have to enter each pid separately (did this for hundreds of Desert Island Discs and it was a chore).

Is there any way I can use a url or series type command that will make the job easier?

Thank you.
