Really poor public domain version available online

Mary Pick Foundation and Paramount has collaborated for the 2K restoration (see trailer) but no releases

HDR/grading: nice, but some blown out
Encoding: inconsistent, smeared motion
DNR: inconsistent, frozen
Old Paramount Blu-ray is arguably a solid alternative choice

Paramount 4K Blu-ray mono

Paramount 4K Blu-ray mono is different version of the Blu-ray mono from the same old 2000 DVD transfer.

The 5.1 remix on the 4K Blu-ray is an appalling remix done by going wild with artificially generated stems from Park Road Post who were given the surviving mono to separate. The experience is jarring and fidelity to original mix in terms of level balance, directionality and impact is nonexistent. Not only does this sound painfully weird, but the Paramount mixers then did whatever they wanted in terms of LFE, sound pans and effect changes.
The original mono mix was not restored and still needs it badly. The 4K master is filled with frozen grain examples coming and going plus some HDR issues in addition to the usual Paramount problems. It is simultaneously better and worse than the Blu-ray master.

Paramount Complete Series Blu-ray has horrible AI upscale throughout even for extras, even though the original TV were shot in 35mm.
The worst AI upscale in S7 disc 1can actually be replaced for free through MovieZyng (doesn't need to purchase through MovieZyng), but that's only one disc, and it only updates The Lucy–Desi Comedy Hour S1E1 Lucy Takes a Cruise to Havana see caps of comparison https://slow.pics/c/1O2fCeuB

2023 Paramount Blu-ray or Eureka MoC Blu-ray

USA Paramount has the best video transfer with the least amount of artifacts: https://slow.pics/c/sjZ3mqF6

Olive Films Blu-ray and Eureka MoC Blu-ray are sourced from the same restoration and are both very good.

Apart from some mild attenuation, the audio is the same on all releases of the newest restoration and is relatively untampered with: https://slow.pics/c/bWF9EGuM

Paramount 4K Blu-ray see caps

Kino Lorber 4K Blu-ray is a fine release with no glaring encode issues, the new master is also fine but graded to look quite dim in HDR/DV. Unsure whether that's really respectful to the source

Kino Lorber 4K Blu-ray / Paramount EU Blu-ray

Old Warner Bros US release is inferior.

2024 Paramount "Presents" 4K

Although there are reviews that called it disappointing. It is also regarded as a vast improvement over all previous versions by many others as well.

This is a problematic release, because while scenes like the aerial shots at the beginning looked pristine and shows new detail, many others are suspiciously identical across all three Blu-ray releases (the 2012, 2020 and this 2024).

Some defects on this are unfixed from the 2020 Blu-ray for some reason. (See this review and its discussion.)

1996 Paramount Hi-Fi VHS

Paramount Complete Series Blu-ray has horrible AI upscale throughout even for extras, even though the original TV were shot in 35mm.

2014 Criterion Blu-ray is from the same master and has only slightly worse compression. JP/DE/FR releases all have incorrect levels. Caps

All Blu-ray releases are from the same mastering, superior to the one on older DVD releases which is sourced from a higher generation source. They all sound about the same, with the exception of Criterion, which sounds worse due to extraneous filtering.

Paramount's disc also includes a contemporary English dub, previously unreleased on home video.

Mono from DVD

Same master, but less bitrate starved.

1980s Paramount VHS

The encode on the BD is preferable to the UHD. Same master, but less bitrate starved: https://x.com/SadHillDevan/status/1530057783885721607?s=20 and see caps
