To make a video "private" or just give access to people who purchased the live class or a specific package, we recommend pricing it really high, to turn away other possible clients. Then you need to publish the video to your studio.
Please make sure that your package has that specific video attached to it so the clients who have purchased that class can access it for free.
On instructions for how to publish the video to your Video Library please see: http://help.powhow.com/entries/23441661-How-do-I-Make-Class-Recordings-Available-to-my-Live-Clients-
