Well the current digital pictures are good, but compared to good quality analogue picture is poor, apparantly when you watch HD, the picture is very clear with no pixelation.
Well the compression artefacts in HD are smaller - because the samples/pixels are smaller. However you can reduce the picture quality of HD in just the same way as you can SD - by over-compressing and having too many compression stages in the distribution chain.
The Athens Olympics were covered partially in HD - and in the US there were complaints that the picture quality was less-than-idea because of over compression, tied in with a dodgy distribution chain. The source pictures were stunning - what got to people's screens wasn't ... It had excessive blocking on fast motion...

I can't see what all the fuss is with HD, I think my digital picture is quite good anyway - compared to what I used to get on terrestrial analogue.
Are the main electrical chains (such as Dixons, Comet etc) now showing demonstrations, because I wouldn't mind going to see one - then I might have a bit more enthusiasm for this "great TV revolution"
