After trying out those settings in my DVD player, they did not display correctly. They were close though.

My revised settings are:
video_size=720x360
sar=0.89
and lavfi:
crop=w=720:h=360
(Make sure the frame size settings are disabled.)

This works because the original pixel aspect ratio is higher than it is wide. I found the value for sar=0.89 by trial and error, so it may not be the most precise.

After many more tries, this is what I found that gets the result I was hoping for:
video_size=640x360
sar=1
and lavfi:
crop=w=720:h=360, scale=720:-1, setdar=16/9

I probably didn't go about it the correct way, and I haven't tried it on any other device, but at least on the computer it looks correct.
Turns out the pixels are taller than they are wide for these DVDs I'm working with.

Sorry. I never scrolled down past the list of available output video codecs, so I never realized it has more example settings. That's my fault.
So, I've have now tried adding sar=32:27 alone and then a bunch of other variations.
They're still yielding oddly stretched results.
I think I'm closer.
aspect seems promising. There has got to be a combination of sar, aspect and lavfi: crop that will do the trick.

I have a trilogy of movies that are filmed in 2.40:1 aspect ratio but contained in standard DVD 4:3 aspect ratio. On playback in a standard DVD player, there are black borders on all four sides.

SVP is great at manipulating it so that I can get rid of the two side black borders upon playback. That is not enough though. I want to be able to transcode it into 16:9 aspect ratio, so that I have a copy that works on everything I might play it on.

I've tried setting a number of the frame size options, but the end result is always stretched in some extreme way.

In the attached screen shot, you can see that it's setting the resolution correctly, but when it completes, the log shows that it was ran with 'format=dar=1.33333' as one of the commands. That is the display aspect ratio for 4:3.
