While you will burn the same calories either way, you will get more health and fitness benefits by keeping your heart rate elevated for longer. I agree with the general consensus of skipping the cooldown and stretching between videos - keep this for the end of your workout.
I disagree with the suggestion that 10 minute videos with a break in between is interval training. Interval training generally consists of much shorter intervals - one minute of intense, followed by 2 minutes of slower paced recovery is typical (although 10 seconds of intense followed by 20 seconds recovery is also used by some as a technique).
The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.
