Not a direct respons, but I think I have come a step forward via a five years old ffmpeg bug report: https://trac.ffmpeg.org/ticket/6782 Doesn't produce MPEGPS-MPEG-2-LPCM compliant output (-target, -f dvd, -f vob). Buffer underflow appear. pcm_dvd added; mpegps -target removed There is obviously a deticated "pcm_dvd" codec for ffmpeg, correspondingly to the later "pcm_bluray". So I verified this on my ffmpeg 5.1.2 built from Packman for Tumbleweed and found: ffmpeg -hide_banner -codecs | egrep "pcm_bluray|pcm_dvd" DEAI.S pcm_bluray PCM signed 16|20|24-bit big-endian for Blu-ray media DEAI.S pcm_dvd PCM signed 20|24-bit big-endian Transcoded input raw DV with PCM audio to MPEG-2 video pcm_dvd audio in a VOB/MPG format: ffmpeg -hide_banner -i dv01.dv -c:v mpeg2video -refs 1 -bf 2 -b:v 8M -maxrate 8M -minrate 8M -bufsize 20M -muxrate 11M -dc 10 -c:a *pcm_dvd* -f vob -flags +ilme+ildct dv01.mpg ............ still a lot of [vob @ 0x562a8c68f240] buffer underflow st=1 bufi=1392 size=2008 Last message repeated 6 times [vob @ 0x562a8c68f240] buffer underflow st=1 bufi=1396 size=2008 frame=14912 fps=298 q=3.9 Lsize= 703652kB time=00:09:56.48 bitrate=9663.9kbits/s speed=11.9x video:582644kB audio:112007kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 1.295818% du -sh *.dv *.mpg 2,0G dv01.dv 688M dv01.mpg Verified that the ffmpeg *dv01.mpg* output file contains *pcm_dvd* ffprobe -hide_banner dv01.mpg Input #0, mpeg, from 'dv01.mpg': Duration: 00:09:56.48, start: 0.540000, bitrate: 9663 kb/s Stream #0:0[0x1e0]: Video: mpeg2video (Main), yuv420p(tv, bottom first), 720x576 [SAR 16:15 DAR 4:3], 25 fps, 25 tbr, 90k tbn Side data: cpb: bitrate max/min/avg: 8000000/0/0 buffer size: 20004864 vbv_delay: N/A Stream #0:1[0xa0]: Audio: *pcm_dvd*, 48000 Hz, stereo, s16, 1536 kb/s The DVD structure and video files from DeVeDe is now being transcoded from pcm_dvd to AC-3 audio: tree ./dv01_tw_DVD -sh [4.0K] ./dv01_tw_DVD ├── [500M] dv01_tw_DVD.iso ├── [4.0K] dvd_tree │ ├── [4.0K] AUDIO_TS │ └── [4.0K] VIDEO_TS │ ├── [ 12K] VIDEO_TS.BUP │ ├── [ 12K] VIDEO_TS.IFO │ ├── [ 32K] VIDEO_TS.VOB │ ├── [ 18K] VTS_01_0.BUP │ ├── [ 18K] VTS_01_0.IFO │ ├── [3.1M] VTS_01_0.VOB │ ├── [ 32K] VTS_01_1.VOB │ ├── [ 24K] VTS_02_0.BUP │ ├── [ 24K] VTS_02_0.IFO │ ├── [ 32K] VTS_02_0.VOB │ └── [496M] VTS_02_1.VOB ├── [4.0K] menu │ ├── [1.9K] menu_0_active_bg.png │ ├── [ 61K] menu_0_bg.png │ ├── [3.1M] menu_0B.mpg │ ├── [3.1M] menu_0.mpg │ ├── [1.9K] menu_0_selected_bg.png │ ├── [1.7K] menu_0_unselected_bg.png │ └── [ 451] menu_0.xml ├── [4.0K] movies │ └── [496M] movie_0.mpg └── [4.0K] xml_data └── [1.7K] dvdauthor.xml 7 directories, 21 files ffprobe -hide_banner dv01_tw_DVD/dvd_tree/VIDEO_TS/VTS_02_1.VOB Input #0, mpeg, from 'dv01_tw_DVD/dvd_tree/VIDEO_TS/VTS_02_1.VOB': Duration: 00:09:56.49, start: 0.534667, bitrate: 6970 kb/s Stream #0:0[0x1bf]: Data: dvd_nav_packet Stream #0:1[0x1e0]: Video: mpeg2video (Main), yuv420p(tv, progressive), 720x576 [SAR 16:15 DAR 4:3], 25 fps, 25 tbr, 90k tbn Side data: cpb: bitrate max/min/avg: 7500000/0/0 buffer size: 1835008 vbv_delay: N/A Stream #0:2[0x80]: Audio: ac3, 48000 Hz, stereo, fltp, 224 kb/s ffprobe -hide_banner dv01_tw_DVD/movies/movie_0.mpg [mpeg @ 0x555ff4407ec0] start time for stream 0 is not set in estimate_timings_from_pts Input #0, mpeg, from 'movie_0.mpg': Duration: 00:09:56.49, start: 0.534667, bitrate: 6970 kb/s Stream #0:0[0x1bf]: Data: dvd_nav_packet Stream #0:1[0x1e0]: Video: mpeg2video (Main), yuv420p(tv, progressive), 720x576 [SAR 16:15 DAR 4:3], 25 fps, 25 tbr, 90k tbn Side data: cpb: bitrate max/min/avg: 7500000/0/0 buffer size: 1835008 vbv_delay: N/A Stream #0:2[0x80]: Audio: ac3, 48000 Hz, stereo, fltp, 224 kb/s Unsupported codec with id 98312 for input stream 0 I looks like DeVeDeNG version 4.17 possibly doesn't support pcm_dvd yet.

With DeVeDe I managed to create the video DVD structure and ISO, and it offered to burn the iso with K3b automatically, With its Property/Misch buttons the selection in the middle offered: *Repack audio and video without reencoding (Useful for VOB files)
The problem is that the Audio (PCM) disappeared from the dv28.mpg input file

===== If you use Mplex for muxing then Mplex will abort with a message that it cannot recognize the audio stream. This is an Mplex issue. It is no problem for Mplex to mux an LPCM audio stream, but the file must have the extension "lpcm". You can verify this by renaming the audio file in the DVDStyler cache folder and give it the "lpcm" extension. Then feed the video and this renamed audio stream to Mplex for muxing, and you will get a perfect MPEG2 file with PCM audio.

apparently you must use one big mpeg file in this case

Well folks(?),
No responses but I appear to have made some headway, which I'll share here in case someone's out there somewhere scratching their own head over this.
The problem seems to have to do with dvdauthor's STC discontinuity at the chapter points when it's fed one file per chapter; the initial pts/dts values are reset, and this somehow throws things off during playback, even if audio and video endpoints are perfectly aligned.
If the whole titleset is mplexed as one mpg and then dvdauthored with chapter- point offsets, the gaps disappear. Also, if the chapter points aren't aligned to GOP boundaries, dvdauthor will do it anyway and shift them backwards.

I hope this workflow is not bitrotted. According to man page from https://linux.die.net/man/1/mplex mplex accept lpcm params:
===
*L|--lpcm-params* /samples_per_sec:channels:bits_per_sample/ [, /samples_per_sec:channels:bits_per_sample/ ...]
A comma-seperated list of paramter sets for the lpcm audio streams (given in the order the lpcm streams appear on the command line). Each parameter set comprises the sampling rate in Hz, the number of channels, and the number of bits per sample seperated by colons. For example, the default 48kHz two-channel 16-bit audio would be specified as 48000:2:16.
Note: these parameters are necessary because mplex expects raw LPCM audio data without any headers. That is: for each sample point a group of 16,20, or 24 bit amplitude values, one for each channel. Amplitude values are signed with the constituent bytes in big-endian (most significant bytes first) order. For 20 bit samples I am not sure but what documentation I have suggests such samples are padded at the lsb end so that they byte-align at the most significant bits.

some more reading from 2005-6 era.
Not a direct respons, but I think I have come a step forward via a five years old ffmpeg bug report:
https://trac.ffmpeg.org/ticket/6782 Doesn't produce MPEGPS-MPEG-2-LPCM compliant output (-target, -f dvd, -f vob). Buffer underflow appear. pcm_dvd added; mpegps -target removed
There is obviously a deticated "pcm_dvd" codec for ffmpeg, correspondingly to the later "pcm_bluray". So I verified this on my ffmpeg 5.1.2 built from Packman for Tumbleweed and found:
ffmpeg -hide_banner -codecs | egrep "pcm_bluray|pcm_dvd" DEAI.S pcm_bluray PCM signed 16|20|24-bit big-endian for Blu-ray media DEAI.S pcm_dvd PCM signed 20|24-bit big-endian
Transcoded input raw DV with PCM audio to MPEG-2 video pcm_dvd audio in a VOB/MPG format:
ffmpeg -hide_banner -i dv01.dv -c:v mpeg2video -refs 1 -bf 2 -b:v 8M -maxrate 8M -minrate 8M -bufsize 20M -muxrate 11M -dc 10 -c:a *pcm_dvd* -f vob -flags +ilme+ildct dv01.mpg ............ still a lot of [vob @ 0x562a8c68f240] buffer underflow st=1 bufi=1392 size=2008 Last message repeated 6 times [vob @ 0x562a8c68f240] buffer underflow st=1 bufi=1396 size=2008 frame=14912 fps=298 q=3.9 Lsize= 703652kB time=00:09:56.48 bitrate=9663.9kbits/s speed=11.9x video:582644kB audio:112007kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 1.295818%

I looks like DeVeDeNG version 4.17 possibly doesn't support pcm_dvd yet. To get this clarified I have written to the author to try to get this clarified. My first impression of this program is that I got taste for its simplicity and straight forward use, yet relative comprehensive behind the buttons.
https://gitlab.com/rastersoft/devedeng https://www.rastersoft.com/programas/devede.html https://www.xmodulo.com/create-video-dvd-linux-desktop.html
Documentation for the legacy DeVeDe 3.9 version https://www.rafalinux.com/?page_id=248
So the question in the mean time is: Any other PCM capable DVD authoring program that can load the pcm_dvd enabled .mpg file and create the DVD video structure and iso from it? I shortly tried DVD Styler, ManDVD and Bombono DVD, but got lost in their forced project start.
DeVeDe: So I installed and tried "DeVeDe(NG)" - a "Video DVD creator" program I had never heard about before recently https://www.xmodulo.com/create-video-dvd-linux-desktop.html
With DeVeDe I managed to create the video DVD structure and ISO, and it offered to burn the iso with K3b automatically, With its Property/Misch buttons the selection in the middle offered: *Repack audio and video without reencoding (Useful for VOB files)
The problem is that the Audio (PCM) disappeared from the dv28.mpg input file
The burned DVD from iso:

To update and round off this thread, I have succeeded to create a DVD Video with PCM audio structure and iso by applying another ffmpeg command line based on a WinFF DVD HQ preset and next DeVeDe. Then I burned the iso to a DVD+RW disc. My DVD player recognized it as a DVD video, but wouldn't autoplay it beyond the start DeVeDe disc logo, if it was due to the disc type or lack of remote controller. But my Samsung BD-player did autoplay the DVD video and also the indexed 5 minutes chapters worked. So I think this is a proof of concept that the DVD Video with PCM worked. As I also this time had some questions to the ffmpeg procedure, I have posted these on the ffmpeg-user mailing list; though no one has replied to it so far. Yet, for those here that might be interested, can find it following this url, without repeating it here.
