PathCamera jumpiness

I've been trying to use the new PathCamera code to move the player around a level in small hops by dynamically generating the next node in the camera's path. It works just fine - however, *sometimes* the camera seems to 'jump' ahead instead of smoothly moving from one point to the next. I tried adding multiple points in between the start and end point but that did not seem to help.

Any suggestions on what could be causing this or how to work around it?

Thanks,
Keith
