You wanted me to post examples of the DVNR-smear on the '97 LD, here are some examples.
Top: US '97SE LD - 4102985 / Bottom: SWE LD (technidisc)
I was wrong about the artifacts I mentioned on the blockade runner-shootout also appearing in the '97 broadcasts, they are not affected by this, take a look at these nasty artifacts.
SWE LD (technidisc) - the first laser blast when the stormtroopers comes through the door
the same frames on the '97SE LD
GOUT is also affected, but not as bad as the '97 LD
and this is how it continues on the '97 LD, I'm actually not sure what caused some of these artifacts, some look like DVNR and some do not. Judge for yourself on this series of frames:
Top: SWE LD (technidisc) / Bottom: '97SE LD - Black fire...
