Wide Screen Review is NOT qualified to comment on the quality of a 35 mm master
film element when it comes out on DVD. MPEG smearing artifacts and some
"pixelisation" present on a DVD are are NOT indicative of any Noise reduction
artifacts present in an Electronic file generated from the DI or from a film
transfer of an Interpositive element usually used for DVD mastering.
I totally agree with Mark Wielage that it is possible to apply Noise reduction
in Non real time that has NO visible artifacts in the final product. I will say
also that without comparison with the original image even the trained eye cannot
identify grain reduction usage when properly used and designed in either
hardware or software.
I saw "OPEN RANGE" on film and saw NO visible grain reduction artifacts.
