DNR it's the problem, and not the technical stuff guys who worked for Shepard.
The DNR software analyze frames to find what small particles are static and shat mall particles pops in just one frame. It find and erase small particles that appears in just one frame.
In 20 fps there are repeated frames, or combined frames, and the software thinks it's not a dust particle.
You can blame the DNR software, but not David.
About clean by hand ??? It would require a lot money...
If this was a 2K film scanning restoration and not a HD transfer remastering, there would be no such problems, but it would be more expansive. David could do 1 great restoration, instead of 3 or 4 fine editions.
Would you prefer a lot less silents films to enjoy on DVD and Blu Ray, just for perfectionist reasons ???
Well, despite of all digital stuff of today, like DVD, Blu Ray, ipods, the video it's still video, it's still the crap old video signal, video field principles, and not trully digital image, not digital frames.
Until someone have courage to vanish the video principles and state digital frames principles, for TV and for home cinema, there will still be the curse of video fields and all crap related to it.
With true digital TVs and true digital frames, would be possible to set any film speed we wish, cause the digital frame speed would be changed without he silly need of repeat or interlace images.
The sad thing is that HD TV it's still replacing old system, but cares the same video principles of annalogic video.
That's why I insist to say: DVD and Blu Ray films are not trully digital.

Keep thinking...
