B767 flight crew experiences loss of the center hydraulic system two hours into a long range flight. When the flaps are extended using the alternate flap switches a le disagree is encountered immediately and dealt with using QRH procedures. The te flaps exhibit the same malfunction after 5 degrees of extension; resulting in landing in this configuration.
