There is a
thread discussing it, but it kind of got derailed a bit. I have not seen the video, nor do I want to. I avoid the televised news, mostly because I feel it is a bit biased and reports their analysis of the events. I like to draw my own conclusions. I tend to read news websites - CNN, BBC, etc.
I cannot tell you how the broadcast media is playing it. I doubt they would air the video, other than small (carefully selected) bites that do not show anything other than a "before" shot, framing him with his kidnappers / executioners.
I would
guess that the broadcast media would be doing a lot of personal interest background stories: family reaction, family history, Bush saying this has to stop, if you are lucky international reaction.
