I agree
In my last set of tests, the 3 hour setting showed no significant difference
from the 1 hour setting for a digital broadcast, played back on a 32"
screen. Both of these were compared to the original witn no real loss of
quality. For standard cable tv, the starting signal is not quite so good, so
you could go longer without noticing the quality drop.
There seems ot be a lot of 'overkill' on the newer standards and components.
But, if you are watching close up to a 42" set, you may be able to see the
differences on a test, but who watches any real programming up close like
that? Even with my new glasses I have trouble making out the detail at a
comfortable viewing distance when watching a dvd, so a small loss of detail
on a recording is of no significance.
