If you are still unsure, the best way to identify whether you need to play something as Dolby A or Dolby SR is to run a reel and listen. Stand in the room where the film is being played, close enough that you can hear well. It's harder to do this using a booth monitor. Have someone else switch between A and SR if you cannot do it yourself while in the auditorium. Follow the below tips and it should become fairly obvious what is correct.
