Well, this is interesting. . .
It seems a well-respected video editing researcher has analyzed the tape of bin-Laden from the 9-11 anniversary and it appears to be a very badly-spliced mock up, rather than an authentic bin-Laden tape. Why would that be? He notes that, among the more obvious problems with the video, all of the segments where bin-Laden discusses current events are still-frame images with audio over-dubs. This leads him to suspect either audio splicing or possibly a bin-Laden voice impersonator or some combination thereof:
On the Friday before the sixth anniversary of 9/11, Osama bin Laden appeared in a new video, his first since prior to the U.S. presidential elections in 2004. In analyzing the video, Neal Krawetz of Hactor Factor, an expert on digital image forensics, said in his latest blogs that the video contained many visual and audio splices, and that all of the modifications were of very low quality.
Most striking is bin Laden’s beard, which has been gray in recent images. For this video it is black. “As far as my tools can detect, there has been no image manipulation of the bin Laden portion of the image beyond contrast adjustment. His beard really does appear to be that color.” The Washington Post has the full video here.
