When im watching DVDs this starts high and slowly reduces to zero(i guess because its high in the beginning and then drops to 0 and slowly brings down the average). If this is zero it means that there is not time between frame deliveries? Jitter sounds like something bad, but a little between framedeliveries sounds okay if the time fits with the intended time between frames.
DVD menus might have static parts and that will cause the average avlue to be high at the beginning.
