Coaches film and all 22 are used interchangeably, although technically the all 22 is a different view than the high end zone coverage that is also part of the coaches film. You can subscribe to see them for every game at NFL.com.
I actually had NFL.com coaches film at one time. You had to wait to watch the film however, I think until wens. Hated the wait, I wanted to rewatch the film ASAP, by wens. I was on to the next game, so half the time, I didn't even watch the film. Which is why I dropped it.
