Record OnDemand Video Online (Iplayer, ITV Player, etc)

Hi

I was wondering if anyone knows how to download ondemand video from ITV, C4 and C5?

I have been downloading BBC IPlayer content using GetIplayer, and deleting them after 30 days (to stay legal)... I download them for use on portable devices so i can watch whilst on the way to work, for example.

Thanks
