You have to make sure the UVs are implicit and you have to re-project a
sequence that is 10-20% bigger on the sides (or more depending on the
speed and motion - your first pass is 20% wider and taller pixel-wise
than the final re-projected pass) so that the object can get it's
shading before it gets into the screen. This way the re-projection
should work.

When using ReProjection with displacement how do you get the Camera
Projected UV to evaluated after the objects are displaced?
By default XSI displaces after the Camera Projection UV has been
sampled so you end up with a an image with displacement being
re-displaced. I've tried switching from explicit to implicit and it
kinda seems to work. But if the object is 100% off camera at the start
of the shot Implicit UV's screw up the re-projection.

There was a good summary of the options a while back posted by
Harry Bardak, I simply copy&paste:
Option 5 :
Camera projection technique. It's a 2 pass approach. First you
calculate you image without Motion blur then you camera project
the result with a constant shader. The motion blur will be very
fast in this case.
