If this is about twin projector dissolve (using RBT projectors) then the
only way that I could see a problem is if the slides were badly mounted. Top
quality and correctly mounted slides presented using twin RBT projectors and
a Bässgen or similar controller is, in my opinion, the true state of the art
for 3D projection of RBT mounted slides.

As to why this does not affect George - well I do believe that one of the
curses of 3D is that those who practice it constantly have very flexible
eyes that can accommodate all sorts of mounting, excess separation and other
defects that can screw the eyeballs out of some newcomers. I also think that
dissolving (or quick changes) between poorly mounted slides exacerbates this
problem.
