So it allows you to watch and listen the way the way you want. There's a skip forward button (15,30 or 60 seconds) so you never have to watch another bloody commercial ever again. You can pause live TV, or get instant replay. Of course this applies to the UK (and you have to be in an area with digital reception). It's like having one of those Sky-plus boxes they are always banging on about, but without having to give that nice Mr Murdoch any money.
