I start a new thread on this topic because the previous one became long.
This time as a procedure to convert HDV video and copy MP2 audio to a DVD-Video compliant MPG file, by applying optional free tools
=========================================================
HDV to DVD 16x9 video using FFmpeg, DevedeNG and Xorriso
=========================================================
1) Concatenation hdv clips:
cat hdv01.m2t hdv01_01.m2t hdv01_02.m2t hdv01_03.m2t hdv01_04.m2t hdv01_05.m2t > HDV01-2007.m2t
du -sh HDV01-2007.m2t
12G HDV01-2007.m2t
</pre>

<pre class="moz-quote-pre" wrap="">
Guess we should be thankful than transport stream (or even mp2 codec
- may be it was one reason why it was chosen over mp3?) quite
forgiving for such operation, even if ffmpeg complain a bit during
conversion ...

<font size="2">Yeah, I am. It is not a real issue, and I',m happy
cat do the job. <br>
The Datavideo DN300 DV/HDV recorder I use(d) to transfer from
camcorder tape, uses a FAT32 file system and cut the video
(stream) over IEEE1394 in 2.0 GB clips each.<br>

<br>
I have also tried ffmpeg's concat protcol, which output similar
messages already during concatenation<br>

2) Converting HDV video and copying MP2 audio to a DVD-Video compliant MPG file by applying and customizing a WinFF DVD Widecreen Video profile
Suggestion to a cleaner output? Some are expected due to joining unclean clip cuts.
But what cause "Multiple -c, -codec, -acodec, -vcodec, -scodec or -dcodec options specified for stream 1"?

------------------
Tested the DVD-Video disk playback ok in a DVD standalone player and ditto BD player.
Visual impression:
HDV down-conversion (oversampling) to 16x9 DVD-Video results in noticeable better quality than former DV source.

well, we bet 2x more pixels on each dimension SHOULD make some
difference :) But nice to have visual conformation
that even with donconverting / downscaling to same size bigger source
actually provides some benefits ...</pre>

<blockquote><font size="2"><i>When you acquire footage in HD, you
record more picture information than when you record in SD. As
a result when you downconvert HD footage to SD, you starting
with more picture information, so your image will look better
than if you recordered in SD in the first place. This process
is called oversampliing and it's another benefit to investing
in HDV, even if you still primarily deliver SD projects.</i><br>
