Source video is 848x356 h.264 MOV.  Using ffmpeg to convert to MPEG2. Certain
pixel heights produce green output.  In my test case, a height of 454 works and
a height of 453 produces green video.

These work fine:
ffmpeg -i input.mov -r 24 -s 1080x454 -an -vcodec mpeg2video -f vob output.mpg
ffmpeg -i input.mov -r 24 -vf "scale=1080:454" -an -vcodec mpeg2video -f vob
output.mpg

These produce green output video:
ffmpeg -i input.mov -r 24 -s 1080x453 -an -vcodec mpeg2video -f vob output.mpg
ffmpeg -i input.mov -r 24 -vf "scale=1080:453" -an -vcodec mpeg2video -f vob
output.mpg
