Can the techniques you use for adding grain be used in real-time when viewing a Blu-ray on a PC? There's a lot of discs out there that would probably be more pleasing to watch if their damn DNR was mostly hidden.
VLC and MPC-HC (with addons) can both add grain in real-time. This goes a long way toward making DNR'ed stuff look slightly more watchable. Hides macro-blocking too.
