John,
You can probably accuse me of fuzzy thinking here.
A thought fell out of my head while reading your post. Is it possible
that pedastal/set up protects us to some extent? In Japan and many PAL
countries AFAI recall Black is 0 IRE while NTSC with the exception of
Japan has 7.5 IRE of setup for black. This would also suggest that the
potential for harm here is increased by the transition to Hi-Def. ????
Wilson?
