I think you need another software like (q)dvdauthor or
dvdstyler to make DVD - they use *program* streams, not
transport streams as tsMuxer creates ...
I thought first to use mkisofs, but didnt really find out the
relevant syntax to make a video dvd iso from the ffmpeg
created dv28.mpg file with pcm audio.
Had a quick look in DVD styler, but for audio it seemed to
support only AC3 or MP2 audio.
I think because project still active you can look at their support
place and see if anyone made request for this already, or if not -
log your own.

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

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.

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:
