Re: Terminator 1 & 2
After reading Bill Hunts post from 5/19/09, I had a thought. Maybe it is the Japanese edition that everyone seems to like which had some sharpening filter applied, and the master used for all of these releases is actually well represented on the Skynet edition. That master may have less grain/noise and be a little softer than people are expecting. The fact that I can spot light edge halos, one of the big artifacts of sharpening filters, in the Japanese capture, also makes me wonder.
To explore this, using screen caps from DVD Beaver, I applied some EE/Sharpening filters in limited amounts to the Skynet Edition frame, and was seeing results that looked very close the the Japanese screen capture of the same frame. It was not exact, and some softer, but still in camera focus areas were never gaining any "detail", but I imagine the processing they use takes advantage of neighboring frames and is a bit more sophisticated than what is available in GIMP. Out of focus objects and the sky were starting to look quite similar to the Japanese screen capture.
Of course, heavy application of the filters creates very obvious artifacts, but with light application, I know I would not be able to tell if the detail I am seeing is real or fake.
What are the telltale signs that the detail in the Japanese release is real, and that the noise is grain as opposed to sharpening/digital artifacts?
My time is limited now, so I can't compose and post illustrative before/after/Japanese comparisons at the moment.

I thought that some sort of detail loss was just a fact of any lossy compression algorithm, AVC included. If DNR is used only to the extent that it becomes less deteriorating than the compression artifacts that would result if it were not applied, I might call that good mastering. I think the better the compression algorithm and the higher the bitrate, the lower the extent of DNR needed to achieve that proper balance.
