Tom Huffman came over tonight to watch the new remaster of Jaws on my Lumagen, Darblet, Sony VPL-vw1000ES chain. For some reason when I switched everything on, the picture was very textured. Turned out the Darblet was set on 120. We quickly cranked it down to 40 and everything was fine. We switched it back and forth from 0 to 40 and the improvement was there.
Source quality, mainly noise in the source, is determinative of how the Darblet can be set.. I do find myself turning it up for live sports and down to say 40 for bluray movies which seems contradictory to the noise thing. But it really does differ. For movies, just set it to where to where you don't notice any enhancement to noise in the picture beyond what you see with the Darbee processing set to 0. Just set it to where you don't see any enhancement to noise. Tom tells me that the Blursay remaster of Jaws is better than seeing the original in a commercial movie theater. On my system it looked simply amazing. Almost like you were there. On the beach, in the water.
