That's where the disconnect is. Noise reduction and edge enhancement post-processing in today's video processors are commonly applied by people like me to SD DVDs only, because SD DVD is already a much less than ideal source. SD DVDs are commonly packed with edge halos and noise other than grain that look terrible when scaled to the native resolution of our displays.
There should be no need to apply these techniques to Blu-ray movies, where high frequency details and film grain ought to be faithfully captured from the get-go.
Those who want DNR or excessive edge enhancement on their BDs should invest in one of these processors so the studios don't do it before delivery. That would be win-win.
