Not the episode 1 video, but the initial video it plays the first time you go into ops? Thanks!
select it and it will play
This going to sound stupid but, select it where?
I would like to know where you find the videos as well. I would like to re-watch the cut scenes that I have already unlocked, but I can’t find them anywhere. 
Strangely, I haven’t been able to watch any of the videos. I’ve played the first two Spartan Ops missions, but I haven’t had a single cut scene yet, and I don’t know if it’s a glitch or if I’m doing something wrong. 
sorry you dont select anything you just push Y where it displays all the episodes.
