Second, the member can ensure the status of a DVD in his/her list. The status can be not shipped, in process of being shipped, shipped, or returned. Netflix ships out the DVD with highest rank directly after receiving a DVD back from the member. When Netflix ships or receives a DVD, it upgrades the list.
