The LD rip I have is missing a bunch of frames. Most of it didn't affect the audio too badly, but I had to patch in around 15 seconds of audio from the UE DVD mono track. I tried my best to make it seamless, but there's only so much I can do. If anyone has a better rip (either synced or unsynced) I'd greatly appreciate you sharing

Regarding CinemaDTS, and just talking general, rather than everyone seemingly resampling the audio, wouldn't it be better to simply flag the video as 24.0000 fps (restoring it to original speed anyway) and then just use the CinemaDTS audio directly instead of resampling it to 23.978etc. fps which can introduce clipping or whatnot potentially (even if likely minor)?

I prefer being able to simply mux the CinemaDTS audio with the existing video and audio tracks, and I've never noticed any issues caused by resampling.

I also considered this when syncing a few audios from 24fps BDs to 23.976fps, and vice versa.

Speeding up / slowing down the video can potentially introduce a lot more extra work. For example, if there's a commentary track or two, now everyone would need to demux and adjust the speed on those as well. Ditto for alternative audio tracks (also possible to introduce artifacts here by the same logic), subtitles, and chapters. So IMO I didn't find it worth the effort, given how unlikely it is to produce and notice any minor artifacts in audio.

Yeah, I guess for something where you need subtitles or where they need to pop up from time to time and the disc didn't use burned in ones it might make it tricky (I might have thought they would sync by frame and not time, but I guess they do by time) otherwise no issue for me. The other stuff wouldn't matter to me. I don't use chapters. If I want to watch with commentary then I can just go back and watch the disc as is. Anyway to each their own, I'm sticking with keeping audio untouched (unless I do it for something where subtitles issues could occur), since the whole goal is to get best original audio and switching metadata frame rate to 24.0000.

Movie: Cliffhanger (1993)
Format: LD [78806] LBX-SRD
Output: FLAC
Synced To: 30th Anniversary UHD (and probably the other UHD as well)

I I think the DTS-HD 5.1 on the UHD is still a better track, it's more dynamic and preserves some high end frequencies better. I think it might be the 70mm 6-track mix but I can't confirm.
I compared a couple different LD's and the 2.0 mix on one of the DVDs and they were all pretty much the same.
But regardless here's the original Dolby Stereo mix from the LD.

The 35mm prints were available with both Dolby Stereo and Dolby Digital (5.1) tracks.

The credits only show Dolby Stereo.

imdb says European prints had Dolby Digital, so it's possible that the 5.1 on the UHD is based of a theatrical Dolby Digital mix.

Cliffhanger was one of a number of titles released between circa 1992-94 to be shown in Dolby Digital (in equipped theatres) but not credited as such on prints or advertising. Stallone's subsequent Demolition Man was another.

I think it wasn't until 1994 that Dolby created the new Dolby Digital Stereo logo that gave an indication of 5.1.
