Tested the original sample script with minimal changes. A lot of buffer 
underflow messages, but the PCM audio stream was muxed and worked in VLC:

ffmpeg -i dv28.dv -c:v mpeg2video -pix_fmt yuv422p -refs 1 -bf 2 -b:v 
25M -maxrate 25M -minrate 25M -s 720x576 -aspect 4:3 -c:a pcm_s16be -f 
vob dv28.mpg

[vob @ 0x562322bbb6c0] packet too large, ignoring buffer limits to mux it
