The one not on YouTube.
I had to check this exactly. Now, assuming the boxed set doesn't have extra footage. It's at 1H41M54S Big Bright White letters saying AGUSTA with the MV symbol in white. (Which is a good thing, because in Technicolour it's hideous.)
If you frame advance it, you can see the characteristic 4 pipes coming out as well.
Plus they sound different. Not sure if the 996 sounds correct, because I don't have a proper sound system setup here, and definately no sub, so playing it, it doesn't have the throaty roar like a normal Duc should, when on my tv.
Whereas the Agusta has those ferrari valve i4 sounds.
