Here's the code line I used and part of the results. I executed the
command two times...the result was the same- video quality is acceptable
but there's a buzzing audio heard. The real audio track is intelligible
but there's still the buzzing sound.

Mine at Mine-mmm:~/Videos/TTS$ ffmpeg -i bia.mp4 -target ntsc-dvd -preset
ultrafast bia.vob
