So the 'DV Luma Correction' does not apply to your situation.

I've seen that. It is indeed related to the libquicktime
build/configuration.

I wonder if that isn't the noise being more accurately encoded.
(The reason I switched encoders should be apparent now if you've
had time to view the sample encodings and test data)

Which says:
DV Color Correction - DV Luma Correction
DV Luma Correction has changed as of BitVice 1.4. If you create
video with iMovie, Final Cut Pro or other programs using the Apple
DV Codec, then check the DV Luma box. The Apple DV Codec
changes luma values when going from RGB to DV ...
Again, this is only for users of the Apple DV Codec.
That's the DV Color correction checkbox option.
The DV Luma Correction checkbox is described thus:
However, NTSC users will find that their DVD may look lighter than their DV
tape did. This is because of a flaw in the way NTSC DV camcorders
output an analog signal. We explain more about that in the discussion
You're using PAL so the checkbox is (or should be as No-Op) not
important.
That's from version 1.4 of the manual. Seems very strange to me
that the software's at 1.7 but the downloadable manual hasn't been
updated (that I could see).
Being in PAL land you do not have to worry about the NTSC setup.

Good enough for DV work but I think that's as far as it goes.

Welcome.
