your comparison pictures prove nothing. You are showing three different dvds from various prints and releases by companies. I see nothing in your pictures that shows interlacing artifcats.
Then you're blind, I thought the screenshot was more than adequate.
Are you sure you know what interlaced noise is?
Yes. Do you?

That's exactly what my screenshot looks like. Frankly your repy is rude and insulting; and you're unfairly dismissive of strong evidence.
For one of the comparision sites you listed the shot of the fire is an extreme example of an interlacing issue ( I still question this because I do not know how this source was recorded). Interlace noise usually gives a blurred image with rough edges or slight line tears roughly speaking. Your Cannibal pic shows none of this, just regular artifact noise from film print and transfer
Unfortunately VLC does not seem to have a feature to "step" frame-by-frame, making it harder to give you an interlace "between cuts" as seen in the example you mentioned. I can however, quite easily, take the same screenshot in powerdvd or MPC to prove the "noise" you're seeing is an interlaced picture:

Non-Interlaced Screenshot
Here are three more interlaced frames:

I'm not providing any more, as you can reproduce this effect very easily, and it's just as easy to prove that most other NTSC DVD's are not interlaced like this one (just pop one in and load it in VLC).
once again you cannot use pc software to judge these things. An ntsc dvd HAS TO BE played back as an interlaced source regardless, even if it was encoded as progressive.
Incorrect. The other two test NTSC DVD's I used in the same conditions did not play back as interlaced.
If you want to make an ntsc dvd and play it back at it's true film speed then the only thing that would ever play it as such would be a computer, because it is not in dvd specification.
Progressive-Scan DVD players play back at the correct speed.
The film framerate if valid, but it has to have the pulldown appiled for ntsc and this is where the interlacing occurs. PAL however is another story.
Pulldown never has to be artificially applied on a computer for playback the way that it does to be output as NTSC to a TV.
Look I am your best bet to test this out and verify and give a true answer. I would be using equipment made for the discs native format.
I'd imagine that your results would be player-specific. Your DVD player may be de-interlacing the source. I don't know what is causing the interlacing on the disc, it may be a mastering error which effects some but not all software and hardware DVD players. If I enable the de-interlace option in VLC the disc plays back correctly - it seems that MPC is also doing this (although it didn't the first time I used it on the disc), and also that PowerDVD does this also. VLC however doesn't try to automatically "fix" the problem during playback if you don't tell it to. Meanwhile you can watch "98%" of your other NTSC DVD's with the factory settings in VLC and no interlacing (NTSC pulldown) will be applied to your video.
As you can reproduce these results on your own on your computer with the VLC player, I see no reason why we need to do anything further to prove what is already stated on other websites - this disc is formatted as interlaced, not progressive. No one's claiming that it isn't possible to watch it in progressive mode, and no one's made any claims as to how many (if any) real-life software and hardware DVD players will be effected by this mastering resulting in an interlaced playback where one would normally expect a progressive playback.
