I saw a "digital cable tv" image of a football (played with a pointed, dark
brown pigskin in the USA) on a 45" CRT tv at an appliance store.  It was a
mess.  Every edge had over-sharpening artifacts and the non-edge parts of
the image had no, (NO) detail at all.  Worst of all, gross pixelization was
obvious from 15 feet away.

I'm not lusting after hi-rez video.  (Hi-res audio, yes though.)
