Saving You Tube Videos for apple TV

Can you save you tube videos so I can store them on an apple TV or itunes?

I am hooked to Britains Got Talent and it would be good if I can save these videos so I can watch on apple TV (Haven't got one but if we could do this then another reason not to get one!, the more we think about it the more reasons we want one)

These performances have me in tears, the welsh opera guy and Connie

Sorry to post all these but I think apple may have something with the apple TV-No longer do you have to be tied to a TV and be dictated by he TV stations.

Thanks I'll take a look- I'm thinking the TV company will take these down so that is why I want to save them!!

Apparently Simon Cowell has signed up Connie for a million or so pounds.
