I'm sure if we could see studio-quality PAL and studio-quality digital,

home, we'd weep at the loss of quality along the way.

PAL was PAL, a good signal, receiver and tube could produce a high
quality and watchable picture in the home, within the limits of PAL
and SD.

SD DTTV produces, at best, pictures that are barely watchable then it
just gets worse. With very little (tending to zero) that you can do
in the way of improving picture quality by improving signal, reciever
or display.

I find that I am much more aware of PAL artefacts (shimmering coloured edges
on captions or other areas of high contrast) than I am of digital artefacts.
Yes, if you analyse a still frame of some movement with DVB-T, there's
blockiness and compression artefacts which you would not tolerate in a still
photograph, but I don't *usually* notice it in a moving sequence.
