Mad Max 2 and Thunderdome 4K/UHDs retired from the market for problems

[Uncle Entity]

Warner messed up the audio for those... as always. They retired the discs, and set a program of product replacement for users who already bought them.
Mad Max 2 has fantastic picture quality, but they used a botched audio track with sounds missing or gravely altered.
Mad Max 3 has fantastic picture, but they used an audio mix with several problems. Less music, altered audio effects. WTF.

From the Blu-Ray.com forum:

"FYI, for all those who are interested. I finally sat down to watch the Mad Max Beyond Thunderdome 4K all the way through and while the film thankfully has not been subjected to the same revisionist foley mixing that Mad Max 2 has, it appears that the 2.0 track on the MMBT 4K is also a downmix of the new Atmos track like with MM2 (and I'd be willing to bet the 5.1 is as well).

Several sounds have been pushed to the forefront of the mix and it doesn't match the sound of the 5.1 from the Blu Ray release.

Examples would be:

1. The music is subdued as Max approaches Bartertown for the first time. The wind is now so overpowering that the music threatens to lost in the mix

2. The buzzing of the Atmoic Cafe sign's flicking is now pushed to the front as well. On the Blu Ray's 5.1 it's heard as part of the ambiance of Bartertown. On the 4K mixes, it's overpowering to the point that it gets annoying. It sounds like a giant buzzing alarm in the middle of the track.

3. In the Thunderdome battle the sounds of Blaster's grunts have been buried and/or removed. Same with some of the snapping noises of Max cutting the bands on Blaster's harness.

4. I could be wrong about this so don't quote me, but I think the sound of Max punching out Savannah Nix at crack in the Earth has been silenced. I'll have to check the Blu Ray again this evening. But on the 4K tracks it sounds like a light scuffle and I remember it sounding like more of a traditional movie punch. EDIT: Just checked, the sound is the same on the Blu Ray. Please disregard.

Overall not happy that they decided to tinker with this film's track too and the 5.1 and 2.0 tracks do appear to be downmixes, but this is still nowhere near the sonic abortion that is the Mad Max 2 Atmos track and downmixes. Here at least the original foley is largely still present and Warner didn't try to make it feel more modern like with MM2. Not great, but not awful either."

Another report:

"Had a listen to the spots you mentioned, and I'm not sure I agree. You're right about those places being a little different from the 5.1 on the Blu-ray, but there are some other spots where there are clearly some extra sound effects in the Atmos that aren't there in the UHD's 5.1 or 2.0.

Jedidiah's flyovers at the beginning (particularly at 3:20 and 4:00) are definitely amped up and embellished in the Atmos, and when Pig Killer is impaled with the harpoon during the final chase (around 1:27:30), there's an extra "crunch" effect of it going through his leg that's not there in the other tracks.

Total speculation here, but I wonder if the 5.1 on the standard Blu-ray was a light remix from the original stems, while the 5.1 and 2.0 on the UHD are the actual original mix(es), possibly with some sweetening here and there. If nothing else, there does seem to be more stereoization in the surrounds on the Blu-ray's 5.1 than in the UHD's. Also, some of the differences in balance between music & SFX could be due to the lossy compression on the UHD."
