Is your reciever able to pass thru a 3d signal? I would try going straight from your xbox to projector first. If your projector has the option to manually go to 3d mode, do that, then load up the movie on vudu. On my system i sometimes have to have all that set up and then load a 3d movie that is on the same disc as a 2d movie. I think the handshake just takes to long between the components sometimes and the player just assumes its not a compatible system. Good luck!
