A member of the official Xbox forums has posted up a list of proposed features for the Fall Update, some of which are ones which sound totally believable such as new screensaver options, compatibility with 3rd party wireless controllers but there is one which stands out like a sore thumb - Xvid support. Could it be that MS will officially support the Xvid support or is this proposed feature a definite give-away that the list is a big fat fake?
