Radio 4 - Taking A Stand - Help Downloading

[richard_get_iplayer]

I'm trying to download some episodes of Taking A Stand from here:

http://www.bbc.co.uk/programmes/b006qvbj/episodes/player

but as they are old episodes, they don't appear when searching with
get_iplayer. 

Can anyone help me download these programmes using get_iplayer or some
other package.

In particular, I wanted to download this programme: 

http://www.bbc.co.uk/programmes/b00g3336

which is only available in Realmedia. How do I get that? Do I need some
other packages installed?

I'm using Ubuntu Lucid.
