Do you have the Dutch version of the 1996 Mark Dacascos movie "Sabotage"? I heard the Dutch release was the only one that was uncut(specifically a scene near the end where a guy gets shot through the head with a sniper rifle, apparently in the Dutch version you see bits of brain dripping down from the windshield) so it would be cool to have that.
There are some Dutch DVD releases of Dingo Pictures movies released by Art Media that you might be able to look out for, but I think all the ones I know of have already been found in ISO form via their German counterparts (check Internet Archive), which should use the same masters between both languages. German and French releases of what I know that currently have not been ripped, Nice Cats, The Hunchback of Notre Dame, Puss in Boots, Dalmatians 2 and Empire of Atlantis (which, again, should use the same masters between all three languages) are known to be available for purchase.

Well maybe this sparks some people to come forward with new things
It looks like you might be in luck. Kiekeboe has released some Dutch DVDs releases of Dingo Pictures movies (including Notre Dame and Atlantis) as well, which may or may not use the masters from the WG, Fun Kid's and Art Media releases.
