They also fail to mention streaming from a PC to Xbox - that has always required an internet connection for some reason. I used to always stream videos from my PC, and if I ever was disconnected from the internet, I'd get a popup saying "failed to download codec" or something like that. As if for every single movie, even if I've already watched it before, has to download a codec. More likely, they were tracking what you were watching.
