Media can be very effective in keeping kids calm and quiet, but it should not be the only way they learn to calm down. Children need to be taught how to identify and handle strong emotions, come up with activities to manage boredom, or calm down through breathing, talking about ways to solve the problem, and finding other strategies for channeling emotions.
Personal Note: Healthychidren.org has a wonderful series of advice for parents. I have saved each of them and have made them available at this link.
