Hey, I wonder if someone can help here: I suspect my horizon disc is faulty, off centred. The drive is really really loud when playing, no comparison to any other game. The whole console is shaking. I am almost sure it is not a vent but the disc.Is this the same for you? Or is your Xbox behaving when playing? I am about to try and return the media, but I haven't had this before... Thanks for any ideas, I appreciate it.
