Apparently Mr. Hopper needs to go back to school. Lines of resolution
are not the same as the number of horizontal lines. Lines of resolution
is a way to say how sharp a video image is from side to side. Amazingly
enough, all cameras for the most part are the same sharpness from top
to bottom. Resolution says how many transitions from black to white and
back again you can resolve across a horizontal line. Theoretically,
you can broadcast approximately 325 lines of resolution and stay within
the bandwidth limitations imposed by the FCC. VHS tape can only record
a theoritical maximum of approximately 273 lines, hence the crappy images.

You might think since NTSC is 325 max, I don't need a camera any sharper
than that, but you would be wrong. You can see the difference between
a 400 and a 500 line camera. You can even see the difference between a
600 and a 700 line camera. The higher resolution you start with the more
generations of copying you can stand. With VHS that number is between 0
and 1 in my book. SVHS with its 400 lines gives you one or two more.

Sorry this was so long but I'm tired of seeing misinformation!
