I am planning to ditch the Media Centre for an Apple TV based on UI alone - it's just too complicated for anyone who doesn't know the set-up.
I've been talking to Philip about this who is *the* man to talk to about all things apple.
He has put me onto Eye TV which he has been testing for a while now.
Philip confirmed yesterday that Eye TV v3 can happily record Freeview HD locally with readily available EPG feeds.
I am planning to hooking that up to a simple antenna, recording shows on the mac and pitching them to Apple TV. More work for me but one less box in the house.
And if enough people ask, Philip can start his own blog so I don't claim his ideas without attributing his input :)
