A system for optimizing bandwidth of a video-on-demand system is provided. According to one aspect of the system, upon receiving a request from a first subscriber for a program, the system delivers the program to the first subscriber via a first communication channel. Upon receiving a request from a second subscriber for the same program, the system delivers only a beginning portion of the program to the second subscriber via a second communication channel and at the same time records a remaining portion of the program from the first communication channel. At the appropriate time, the recorded remaining portion of the program are shown to the second subscriber.
