Help ripping RTMPE stream from www.channel4.com (4oD)

[noobie]

Hi all

I am UK based user who is wanting to rip the following 4OD programme from last night as I am a fan of the band featured in it and want it for my own use. I have Replay Media Catcher but understand that the coding Channel 4 use is not compatible when using it to rip.
I've had a look though as many of the threads here as I can but admittedly I'm not that technically minded and my head's spinning a bit after all this reading.

The video I want to rip is here:

http://www.channel4.com/programmes/bestival/4od#3131875

can anyone help me to rip it or at least explain patiently and as detailed as possible so I can have a go?

Sorry for such a thick sounding first post - thanks for reading
