Comment (by rmk):

 if it is in presentation order then it's incorrect because the pts of the
 first frame in presentation order (which is a B-frame) for the sample and
 all other XDCAM-EX camera samples I have checked is 0 but the field is set
 to the non-zero PTS of the first I-frame which is the third frame in
 presentation order.
