This may sound like a stupid question, but if I was to get a WinTV-HVR4000 will this be able to get the HD terrestrial free view?

All the specs I see for it say it will work with;

– DVB-S2 hi-definition digital Satellite TV
– DVB-S digital Satellite TV
– Freeview digital Terrestrial TV
– Analogue TV

Does the fact that it does freeview digital terrestrial mean it will also do the HD channels or do I need to get a HD box as well to plug into it? 

I'm looking at building a good old HTPC and was going to use this as my TV card, will it do the trick? I have a 1080p TV so want to be able to get the best signals to it.

Cheers
