Yes, the ESA guy in on this site and uploaded it to the video section and it belongs to this site. It was uploaded to youtube without any accreditation.
The full video is on the video section:
http://forum.nasaspaceflight.com/index.php?topic=1815.0The link to the original video is no longer the one shown on the link you posted because someone stole it to youtube.
The thread starter is the person that uploaded it to youtube without permission. I've been posting in his comment section and it was ignored. So it's a bit rich for him to now be asking about who to accredit over a year later. At least the admins here now have his IP details to take action against him now.
Does somebody know what actually happened to the rocket?
I think it was contamination in the fuel pump.
One soldier was killed by flying debris.
Watching the Youtube video I see the strap-on block fall away but I do
not see a disturbance in attitude - perhaps the expect "tilt" was in line
of sight?
I once saw a Proton/Mars failure on video and a major tilt was obvious when one of the 6 engines abruptly failed just after liftoff...........
