I don't know if the bonus DVD came along with the European FFX:I.... but in the Japanese FFX:I, there was an extra DVD that featured some extra stuff, interviews, upcoming games, but the thing that made the DVD worth anything is the "Another Story" section of the DVD.
Since I can't read Japanese for shit, I have to go by what GIA went by. A very interesting scene indeed (this wasn't an FMV btw). This raises the question if Tidus is really alive or not. Using my ultra ULTRA 1337 recording device...

OH YEAH! THATS RIGHT! It's in Japanese! XD Well, that was Tidus yelling the following (which was roughly translated thanks to The GIA)
(Sphere Opening)
"Why the hell did I get arrested for? Let me go already!"
"You hear me, don't you? What'd you think if she was your girl?"
"Who cares if I used the enemy's machina! It was the only way to save the summoner!"
"What would you have done instead?!"
"Let me out of here! LET ME SEE HER!"
(Sphere Closing)
Now that you have that, lets go over some of the stuff.
First off, Tidus is arrested and is in a cage... underwater it seems. We don't know who is this "girl" is or what Tidus is saying about using the enemy machina. All we know that he saved some Summoner's life (could be Yuna) with some Machina. It could be Yuna... a lot can happen during the two years between the end of Final Fantasy X and "Another Story". Yuna could of had her life saved by something... but thats for the next game to tell.
Highlight of the Vid... making fun of Wakka being fat (though I can't really tell at all.), including squick noises!
