[FFmpeg-user] How to convert M2TS BD Video to DVD Video?

I have several homemade, simple Bluray Video iso files based on 
mpeg2video and PCM audio, duration about 3.0 - 3.5 hours each.

Instead of making DVD video options also from scratch, I wonder if it 
easier/possible to convert the SD-BD M2TS files to compliant DVD video?
I would be thankful for suggestions on using ffmpeg procedures for this 

Inspecting a typical SD-BD-video.m2ts by mounting the iso:

    mount SD-BD_DV58_09+DV59+DV60.iso /mnt2
    mount: /mnt2: WARNING: source write-protected, mounted read-only.

    ls -lh /mnt2/BDMV/STREAM
    total 36G
    -r--r--r-- 1 nobody nobody 36G Apr 16 18:58 00000.m2ts

    ffprobe -hide_banner /mnt2/BDMV/STREAM/00000.m2ts
    Input #0, mpegts, from '/mnt2/BDMV/STREAM/00000.m2ts':
