Thank you for sending us a note. There are two separate sections, one is On Demand and the other is DVD. While the titles are the same the workouts are different. In the DVD section , those workouts can be streamed, but they can also be purchased as a DVD for you to own. The On Demand workouts are only available for streaming. Additionally, when you sign up for a monthly On Demand subscription you do not get access to the DVD workouts.
Best of health and hope you enjoy the Powerstrike workouts!
