Yup, if you work for budgetcrappyshoppingtvchannels.tv and you've just
bought a chunk of bandwidth, do you broadcast 5 top quality channels, or 10
pixellated ones? :-)

Usually happens to me when it gets windy, the dish wobbles a bit and the
picture "chops up", mind you I'm receiving the signal quite far away from
where it's aimed at ;-)

The problem in the UK is that they can't wack up the power of the digital
transmitters until analogue is turned off. For example my mum's local
transmitter, Rowridge, gives out 500 kW of analogue signal, but only 2.5 kW
of digital signal. Yet she still receives perfect digital pictures through
the same aerial. Imagine if 500 kW of DIGITAL signal was transmitted - you
wouldn't need an aerial!
In fact, here in Germany in my previous apartment, I could just stick a
small bit of wire in the aerial input and I would receive all digital TV
channels perfectly :-)

There are two free HD channels via satellite (BBC HD and ITV HD, with more
surely to come), if you have Sky there are loads of HD channels for films,
sports etc but of course you need a subscription.
You can get a bluray player for 150 pounds, or just get a play station 3 and
you get an uber amount of computing power too.
