Just tested BD Render with Einhander's latest CinGG built: Jan 19 2024 
The first question is if this "BD creation aspect 16:9 fixes" is 
included here or not?

Loaded a hdv 1440x1080 25i file
BD Render
Format was discovered correct 1440x1080 25i
Scaled (tried also None without difference)

Default playback of bd.m2ts with VLC was visible ok
- that is no visible DAR by changing to 16:9

By verifying the I/O files with ffprobe:

  * Input #0, mpegts, from 'hdv07_05.m2t':
  * Video: mpeg2video (Main) ([2][0][0][0] / 0x0002), yuv420p(tv, bt709,
    top first), 1440x1080 [SAR 4:3 DAR 16:9], 25000 kb/s, 25 fps, 25
    tbr, 90k tbn, 50 tbc

  * Input #0, mpegts, from 'bd.m2ts':
  * Video: h264 (High) ([27][0][0][0] / 0x001B), yuv420p(tv, bt709, top
    first), 1440x1080 [SAR 20833:15625 DAR 83332:46875], 25 fps, 25 tbr,
    90k tbn, 50 tbc

That is for bd.m2ts:

  * SAR=20833:15625=1.3333
  * DAR=83332:46875=1.7777

I would be easier to see/verify if possibly [SAR 4:3 DAR 16:9] simply 
could be used also for bd.m2ts
Else good so far regarding HDV 1440x1024 to bd.m2ts ^
