Wow. I wonder how the formula in the howto was derived.
Offhand I'd say that the formula in the howto section is
incorrect based on the real world numbers above.
And I'll have some numbers too in the near future. I'm running a
set of encodings varying -N and using a good DV capture from an
analog source. So far the pattern I mentioned last night is
holding up though.
Thanks for the numbers!
