Jim,

Thanks for the careful examination and thoughtful comments on the beheading video. I especially appreciated the fact that you made note of the synchronization irregularities. I have not seen the video, only some of the picture frames from it(I tried to find it on-line, but couldn't find a link that worked), and I hadn't realized degree of editing that had been done. Your speculation about the time differences is certainly a possibility--and not one that anyone else seems to have come up with--
