Predicting positions using splines

First off, i don't know much about splines and stuff. I've tried to look at the function that have been lying about, but i just don't get it. I'm trying to predict the players position. I have the last two positions and rotations. Anyone provide any help?

There might be some relevent info here - you'll have to nose through it:
