Comment (by cus):

 Also, the encoder might not be wrong, if the 4:3 content is pillarboxed in
 the 16:9 video.
 In this case the full 720x480 raster has a display aspect ratio of 16:9,
 but the to-be-displayed 540x480 raster indeed has a display aspect ratio
 of 4:3. However, ffmpeg/ffprobe always reports the display aspect ratio of
 the full raster, not the area of the active content.
