Some history on DVD screeners and watermarks:

It mentions the "watermark".
But, it's not like an audible watermark you hear on some streaming sites where they say stuff like "you're listening to a sample on amazon.com" intermittently.
No, this watermark is different.
These, inaudible, watermarks make contact with the original person who legally owns the rights to such content.
In thase, the Guild.
This can't ever be detected by firewalls, antivirus, antimalware. I don't care how smart you think you are with what you download for security software. You'd need something like WireShark to monitor all internet packets to figure this one out.
The Guild can trace back to the original uploader, how they nabbed a couple people who were the first ones to upload the DVD screener.
People who download are not dealt with first. Priorities. :smrt:
These inaudible watermarks come in variations, I believe. Depending which company you go with (and there are a lot of them).
Some will span across the frequency domain, very much like Cinavia for blu-ray.
Converting to a new format will not fix this, at all.
You need to find the exact frequency the watermark is occupying and scrub it.
This means some of the shared audio in the same frequencies will get destroyed, unless you make an effort to try repair with fancy programs and plugins.
You can't really detect it by looking at spectrograms either. You have to know a little bit about this technology in the first place.
That's how they nabbed the guy who uploaded The King's Speech in 2011.

Fast forward to toay: things are changing.
Probably with the aid of DVD Ranger (
https://torrentfreak.com/dvd-ranger-cracks-unbeatable-cinavia-anti-piracy-system-140524/), a program that can remove the Cinavia protection.
But, know also, that this re-encodes audio, even lossy AC3. So you're looking at second generation encode (the first generation encode is the original AC3 track that's converted from the master audio), plus whatever audio has been destroyed due to the Cinavia removal.
I believe this destroys shared frequencies with the Cinavia watermark.
BECAUSE...
Going back to the first article, you see the article mention this about the scrubbed audio of the screeners and their quality:
But movie pirates are now embracing technology of their own and defeating the studios' watermarks. The quality of the scrubbed versions isn't perfect
So, it was more than likely something like DVD Ranger was used.
The group that successfully removed the watermark mentions this:
Movie had Watermarks visible and invisible ones, had to remove frames to get rid of them.
Nothing i havent done before, It was hours of work, but its finally done and here for you to get!
So while some torrents (or direct download sites, or whatever) may have the screener, be absolutely sure of where you are downloading from and whom you are downloading from.
"Several ‘versions’ of the movie exist on torrent sites, each labeled by rival release groups including CM8, EVO, TiTAN, Ozlem and RAV3N"
Who knows if they all use the watermark-stripped version or if they just use the watermark version.
Most groups/scenes don't really need to tell you anything.
Especially on public trackers (torrent sites). They're not obligated to give you details or information.
It's a free site, their time is more dedicated to their home sites where you can get all the details.
DVD Ranger, btw, is not cheap to own. And you can find it in places. But it requires a subscription to successfully remove the Cinavia.
You can find hotfixes for movies, individually from some pirate sites.
But, it's not been updated forever.
I've never used it personally.
But the program needs to access the DVD Ranger database (the subscription part of legitimately owning the program) in order to find a hotfix for newer movies.
It's certainly not cheap. Not at all.
