BBC News 24 interview just now with a journo from Al Jazeera (his name was 'Jihad Ballo', phonetic spelling!!):
Only 14-15 minutes of the tape was actually broadcast, there is more which wasn't used. The journo wasn't able to say what the total length of the received tape was, as he wasn't specifically working on the editing process.
As British chick said earlier, they did seem to be cherry-picking segments for tx, rather than just playing the tape in full.
We have obtained a full human translation of the video and will be posting it shortly.... Stay tuned for more.
In the meantime, you can download the video.
