Is this worth using?

My sets have DNR which can be set to Off, Low, Medium, & High

Im gonna check it out tonight on my Vizio GV42LF 1080p CCFL LCD set tonight.

I have mine turned off, if on I get a strange lag in the backgrounds.
hard to explain but its like DVD noise.
so I would try but for me its off.

Probably better left off, especially if you're just watching blu-ray or whatever; HD material doesn't need NR and analog media is better off cleaned up by older equipment designed with that in mind.

Yeah, well I mostly leave it off or on LOW for DVD, OTA Broadcast, and so on and so forth. But I thought it might be useful for LD.

I'm sure you're right, but with regards to high quality circuit features built in to some players like the CLD-D925, being so outdated especially if used when the player is hooked up to a modern display, it looks awful.

Noise reduction features on LCD/plasma displays are better, but yeah even so, like the others have said I would leave it off.

Maybe on some old super noisy transfers you can set it to 'low' but that would be the only exception IMO.

I meant more like the early DVD recorders and stuff, things where it's pretty much expected for you to use the inputs for VCRs and the like. That's going to do a lot better job with LD than something designed with HD broadcasts in mind.

Yea, understood. I think that 2008 multiple composite, S-Video, and Component inputs were still on board LCD and Plasma TVs and the prices had come down and quality gone up on the deinterlacing and and scaling chipsets by then. The comb filter looks pretty decent from the Snell and Wilcox pattern I saw (on the Vizio GV42LF).

I have a 50" Sanyo LCD. I tried turning its NR to down and it looked like hammered poop: Noisy, grainy, horrid. Maxed it, and the results are much better. The default is midrange, but still is not enough. It doesn't seem to affect sharpness at all, either.
