Isaac,
Did you ever figure out a solution to your ghosting? I’m trying to do a conversion from 23.976 to 25 fps for a PAL release and am getting the exact same ghosting on my clips using compressor. None of my clips are interlaced to begin with and considering I’m only making up for ~1 extra frame I was really hoping compressor would do the trick. I have tried both best and better motion compensation and get the same results.
Here’s a screen grab. Check out the arm. And no this isn’t motion blur because it’s not present in the original clip. Any ideas?

Cheers
