This really has nothing to do with protocols, but I can't let it pass for
a second time...

I can only assume that either that you have never watched scan-converted
broadcasts, or that you are not prone to attacks of sea-sickness.  The effect
is that moving objects (or worse, entire backgrounds) jerk across the screen,
losing all clarity while they "move", but regaining definition when they stop.
The result is extremely disconcerting to the viewer.  It's only to be expected
that the European broadcasting authorities would reject any system which caused
such a gross degradation in quality of service -- indeed, we, as viewers, would
be entitled to feel upset if such a system were ever foisted on us!  625/50
may not be perfect, but it's considerably better than scan-converted HD/60
would be.

[I believe that it is much easier to scan-convert from 50Hz to 60Hz, so that
European material shown in 60Hz areas would look quite reasonable.  However,
this would give a totally erroneous impression of scan-conversion in general.]
