Well apparently it has the codes to all the Stargates, whatever that means. Which obviously means that Satra can invade earth, somehow.
My favourite bit is when a piece of the destroyed Stargate comes through it's own wormhole, and the wormhole stays open. I can't even make up a excuse for that to be possible.
It sounded like the real deal on the first line, but I think it must have been an impersonator for the rest.
The really sucky thing was in Stargate: Unleashed, the mobile phone game. The voice actor who stood in for Don S. Davis had a completely different accent.
