The video looks suspicious. Every time they say Mohammad’s name the lip-synching is off. This leads me to believe that the film was about something else and someone edited it to include Mohammad’s name. It doesn’t even look professional.
Only the final one was forwarded, by persons unknown, to Sheikh Khalid Abdullah the cleric in Cairo who aired it on TV. Nakoula, the maker of the original film, was not the one who uploaded the final version, Innocence of Muslims, to the internet.
You can hear some interesting things about the timeline of all these iterations of "the movie" in the Youtube video linked below. Start at 9:30 and watch to 16:00 for the meat of that.
