Simple as the title says, no matter what video I select, be it Nightfall, Terminals, whatever. It will always load up and play something different, usually a behind the scenes video, and never what I selected.
Ya I had that happen to me, I raged at it too for that. Idk, try resetting stuff or going back to the main menu. Also, if I searched or looked for something i wanted vs playing suggestions, it seemed to work better.
