MGM Blu-ray

Original 4-Track Mix: MGM 1990 LaserDisc

General release mono mix: CBS Fox VHS Hi-Fi but time compressed
5.1 remix of 4-track mix: MGM Blu-ray (a lossless version of the remix from the Ultimate Edition DVD)

The 5.1 track on the earlier THX LD/DVD and SE DVDs is not the same as the later remix, and appears to be more faithful the original mix (likely a simple upmix). The UE DVD remix has a lot more surround activity.

4K Streaming

4K Streaming SDR master seems to be from the same scan and looks like it has less tinkering than the Blu-ray

MGM Blu-ray is the best physical media release

Screencaps of the 4K SDR master: 007 on Home Media: Moonraker (1979)

Dolby Stereo: 1990 MGM LaserDisc
