Recording from a birdbox cam

[steve-h]

I'm not sure if this is the best place to post this, but it seemed to fit the best.

I have one of these: http://www.handykam.com/Wildlife-ca...-white-CMOS-resolution-camer/flypage.tpl.html

I'd like to be able to record what's being streamed to my TV. Halp? :

I have a spare raspberry pi and external hdd, so via that would be preferable.
