Jittery scenes

Nobody has posted anything about the jittery scenes (I counted about 3 I think). Am I the only person that got a DVD that perhaps has problems, or did anyone else notice that certain scenes have camera jitter? The first time I noticed it was during a crane shot, but I thought maybe they used a cherrypicker for the shot, and perhaps it jittered a bit as they were moving it, but then two other scenes which were on the ground or in an office were jittery without the camera moving or with the camera panning very slowly.
