First,
Thanks to all of you who has replied and, excuse my late follow up in
common as follows:

This was a little bit misinterpreted. FFplay and VLC did both playback
the resulting video in .m2ts, but there was no PCM audio encoded.

For BD-RE and DVD+RW direct burning I've used current K3b/Cdrecord and
e.o.l NeroLinux (2010), beside 'dd' and 'growisofs', and also plan to
use Cinelerra-GG 5.1/bdwrite for edited mastering.

Yes, I have realized 'pcm_bluray' (as also 'pcm_dvd') are just ffmpeg
decoders, and that PCM audion cannot just be copied from DV and muxed
into .m2ts.
Yet, I'm surprised, because PCM has been a standard for raw audio so
many years and video generation media, i.e Hi8 since 1989, DV and DVD
since 1995/1996 and Blu-ray since 2006.

Yes, I will also keep my Hi8 and HDV source tapes (the oldest is 25
years), and have converted and imported to .dv, .m2t and also some .mov
(prores hq) files.
In addition I wanted to make playback-able intermediate formats on
Blu-ray discs if possible.

Yes, DV use bottom-field first interlaced, while HDV 1080i use Top-field
first.

Have to study this code more what can possibly be applied in my case.
---------------------------------
So far I have therefore given up to get pcm audio muxed into .m2ts for a
working Blu-ray video.
Lately, I have tried a couple of other approaches, as my Samsung Ultra
HD Blu-ray player among the specs supports .avi and .mkv
DV to AVI
I used ffmpeg to copy and mux both the dvvideo and pcm audio, and this
.avi played ok in VLC and ffplay. Burned the AVI to ISO and UDF discs.
The BR player told 'dvvideo' was not a compatible video format....!
DV audio to pcm.wav
Extracted (copied) pcm audio from DV and it was accepted and worked well
in the BR player.
----------------
DV to MKV
Just to test a .mkv container I used the corresponding code as for the
initial .m2ts in my first post, that is re-encoded the video via x264
and copied passthrough the pcm audio. This format was accepted by the
BR-player and played well, both audio and video.
However, the ffmpeg code needs to optimized for the 576i SD format.
Feedback and suggestions to go further here will be welcome ;)
