Actually if you watch/record ANY live television, doesn't matter if it's BBC, iTV, Sky or Bloomberg you need a licence.
Me, I skipped on the licence as I only want to watch Top Gear & F1, with top gear available after the fact on catch up and the BBC having given up (most) F1 rights to Sky I just wait till after the race and download the Sky broadcast.
I ain't going to pay over £1 per hour of television watched per year. They can get to *bleep* with their "TV Licence" (read TV Ownership Tax).
