That's one possibility but it might not work.  The problem may be the 
relative scales of the scene.  If you scale it down to 95,000 pov units 
you'll want scale the camera position as well which may cause the same 
problems in calculations.  I suspect the problem is having a camera so 
close to a relatively huge object no matter what the scale is.  You may 
have the same problem with an ordinary scene and moving the camera to 
0.00000001 pov units from an object.

Keep in mind, this is educated speculation since I haven't actually 
tested this particular scenario, but I suspect it's causing a problem. 
Try scaling down the world and see what happens, but I suspect you'll 
have the same problem.  Changing EPSILON may be the only realistic answer.
