The artefacts on digital terrestrial, viz. Freeview in the UK, seem to be particularly bad with grass pitches and crowds (focus pulls are also a problem). This spoils my enjoyment of the highlights programmes of football and cricket, and I don't watch very much else. I can't justify the cost of HD/satellite/cable, because I only watch a very few hours a week as it is. Even so, live HD football at the pub has the same problems to a lesser extent. With analogue TV, I get ghosting on some channels, which is also very noticable on a grass pitch. C'est la vie.
