[Cin] Blu-ray compliant MPEG-2 SD video with LPCM audio

[Terje J. Hanssen]

The source video files I want to convert to Blu-ray compliant MPEG-2 SD 
video with LPCM audio are:
1) DV25.dv, 720 x 576 (PAL), 50i 4:2:0 video with LPCM stereo audio
and
2) SD ProRes.mov, 422 (HQ) 19-bit video with LPCM stereo audio

The purpose is to get better MPEG-2 quality using higher (highest) 
possible bitrate than for DVD video.
(Yes, I have tested h.264 via Cin-GG)


Here a sample ffmpeg command script found for HD video with PCM (Blu-ray 
not mentioned):
https://gist.github.com/avoidik/153879c06afdcaad8d69b38bcc00abb7
# with PCM 16-bit audio (uncompressed), constant video bitrate with 
specific bitrate tolerance

ffmpeg -i "input.mp4" \
   -c:v mpeg2video -pix_fmt yuv422p -refs 1 -bf 2 -b:v 50M -maxrate 50M 
-minrate 50M \
   -s 1920x1080 -aspect 16:9 \
   -c:a pcm_s16be -f vob \
   "output.mpg"


Suggestion to FFMpeg command to convert the actual SD video files 
Blu-ray compat?
And if  PCM has to be muxed via MP4(Box) first, a guideline is welcome?
