(France Rimini Editions 4K has heavy DNR)

The DV/HDR grade is tasteful and not overdone. SC has better compression, though not flawless; encoded by FiM, but Criterion also holds up quite well. Both releases claim to be approved by Lynch.

SC has a missing fade that Criterion reinstated.

The film was originally mixed in Dolby Stereo (matrixed LCRS). For the 4K restoration, this mix has been transferred from the original magnetic elements and remastered with Lynch's supervision. Unfortunately, the fidelity suffered in the process, with many sections ending up significantly less detailed due to a noise reduction pass. This track has been altered compared to the original, with reverb added to some dialogue, different ambient sound effects, changed panning, and extended bass.

For the unrestored mix, there are two major options, each with its own merits and flaws. The 2001 Paramount DVD, which I would say is the best well-rounded mastering, and the 1999 Japanese LaserDisc, which has noticeably better clarity and high-end detail, as well as better dynamics, but suffers from occasional distortion and has less bass than the DVD.

The LD also has some ambiance buried too low in the mix, and some dialogue panned more to the centre than the DVD. There are no content changes I was able to find. Unfortunately, I don't know what accounts for those differences.

The other available tracks all have more significant flaws. The Italian and Japanese BDs use the same base mastering as the DVD, but with some patching in a few shots. HD-DVD is sourced from an inferior transfer, the same as the Momentum DVD.

The 5.1 remix, originally introduced on the 2002 DVD, and carried over without changes to the 2009 BD is a light and mostly faithful remix, with fairly minimal LFE and surround use, but still potentially worthwhile as the only discrete track.

Not sure about foriegn

(needs gamma correction)

The movie was shot in HD and  France Potemkine Blu-ray (needs gamma correction) has slightly stronger encoding than Italy Eagle Pictures 4K Blu-ray. Curzon Blu-ray is the worst of all three (not by much) see caps.

The DTS-HD 5.1 on the 4K Blu-ray. The Atmos is compressed. https://forum.blu-ray.com/showpost.php?p=22426684&postcount=840 

The Director's Cut DVD has some exclusive features like an isolated score track.

StudioCanal UK 4K Blu-ray > Kino Lorber US, more extras on the UK disc

2025 reprint is the exact same master as the 2010 disc

(additional scenes appear to be upscaled)

The Paramount 4K Blu-ray has a much better new scan that removes the original extremely dated color grading. This is an improvement on one hand but a definite revisionist change on the other. There is the expected grain management and slight HDR issues in addition to encoding quirks from Paramount. It is a giant improvement over the original Blu-ray but the color change and other issues means that the Blu-ray is one to keep for purists to have the as-is original iteration of the film's presentation. Audio wise the film has been remixed into Atmos but it merely seems like a slightly tweaked and frankly tamed version of the original 5.1. Of the two I prefer the Blu-ray 5.1. The original Blu-ray was Dolby TrueHD and the reissue Blu-ray in the four film Blu-ray collection boxset was DTS-HDMA.
