From what I have heard from others,they noted it sounds like the voices were dubbed in, and possibly over-dubbed. No surprise, as it was likely recorded in English and translated. But If you can dub it once, why not overdub it from "Osama" to "Mohammed"? SO what I'm wondering is: did an industrious al-Qaeda member changed it about to be "insulting", then sent it to the local YouTube to deliberately mislead others?
I believe that's most likely the case, but I also heard the crappy video has been in Youtube since July, so why would a community organizer wait until now? Does the whole middle east sit online and watch Youtube all day?

As film, as drama, it's laughably bad. And its exact provenance still remains a mystery. As far as I know, there is no complete “film,” only this trailer.
What I do know is that this “trailer” has been up on YouTube since July, but that it only came to the attention of Muslims after a radical Islamist TV station in Cairo broadcast and denounced it last week.
