Aynayda ,after seeing both videos involving the 340 and the 777 I can say there was a 'minor' difference...the 777's plugs melted after brakes caught fire,and the fire was not very impressive while the 340's didn't..resulting in tyre explosions ,and very impressive fire.
I doubt Airbus removed the video from the net, others tried to remove videos from Youtube, without success.
And you have to remember it was a test, and this is the reason of tests, to find weak points and eliminate them.
