MPEG-2 Program Stream w/PCM Audio

I'm trying to create an MPEG-2 Program Stream in an mpg wrapper that contains PCM audio. When I run the below command, I get an output that contains MPEG-1 audio.

ffmpeg -i "input.mov" -vcodec mpeg2video -pix_fmt yuv422p -bf 2 -b:v 50000000 -maxrate 50000000 -minrate 50000000 -s 1920x1080 -aspect 16:9 -acodec pcm_s24be "output.mpg"

Does anyone know why this happens and how to get the command working to give me PCM in an MPEG-2 PS file with in an mpg wrapper?

FFmpeg only supports muxing 16 bit PCM in a MPEG2 PS. Use

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

The -f vob is needed to force a MPEG-2 PS, else ffmpeg will select MPEG-1 Systems muxer.
