Okay, I am working with the DVD print now. I am using Sharc's suggested settings, but without the Greyscale and using the FluxSmooth plugin because I can't seem to get Spotless running, and I can't get MDegrain working either, so I left off any sharpeners for now. So, here is a comparison (so far) of what I've got with the DVD and a similar snapshot of the 'finished' HD print. I guess I can see where maybe with some more saturation and if I can figure out a good sharpener, I MIGHT get a better result. But, just as is, you can see the darker outlines, the sharper delineation, and just the deeper, richer colours of the HD print (for now...) There just seems to be more 'substance' there...
