It seems your Sony shows less crosstalk then Joe's JVC projector. Interesting.....
To me, ghosting is the nastiest thing about our current crop of 3D displays. And from what I've experienced, ghosting is almost always a function of the display, with the glasses a much more minor offender. But it's not a simple thing, as you well know, Frank. Your homemade test images were the first ones I used to check the ghosting on my Samsung plasma. I was shocked to see how much actual ghosting there was.
I believe you found much the same level of ghosting on your Panasonic plasma at the time.
JVC engineers made a design decision to use a 96hz frame rate for their 3D projectors (2x24 fps/eye or 48hz per eye, for a total frame rate of 96 fps). For commercial 3D Blu-ray, that was a great decision. Ghosting is almost never an issue for me with my RS40 when I watch Avatar or Monsters vs Aliens, or any other commercial disc with material mastered at 24p per eye. It's a completely different story with material shot at 60i per eye (120hz total), such as the JVC TD1, or 720p 120hz gaming. Ghosting is much more severe at 120hz than at 96hz with the JVCs. OTOH, I seem to recall reading in the Sony thread that some people have had more problems with ghosting on the Sony projector, which I believe only operates at 120hz in 3D mode for 24p content. Don can correct me if I'm wrong about that. AFAIK, the Sony has no 96hz 3D mode at all, just as the the JVC has no 120hz 3D mode for 24p content.
It's an issue of compromises in these first generation products. DLP projection seems to be the technology that's most immune to ghosting, but many prefer the JVCs and Sonys for their better image quality in other areas. I wish we could skip forward a couple of years to the point when ghosting has been eliminated. When we're there, the images from these first gen camcorders will look even better than they do now.
After all, it's not the camcorders that ghost. The displays are responsible for the ghosting we see.
For you, Frank, since you don't watch 3D Blu-ray, and you shoot 60i 3D all the time, a JVC projector would be a really bad choice. That hardly matters, though, because none of the projectors on the market can do checkerboard, which is a very important feature for you. For me, the JVC is a great choice, since most of the 3D I watch is 24p based movies on 3D Blu-ray. I'll watch most of TD1 footage on the Samsung plasma, where it looks great. Meanwhile, I'll have to wait for the next gen of projection technology that ghosts less at 60i. Maybe next year.
