This product is manufactured on demand using DVD-R recordable media. This product is expected to play back in DVD Video "play only" devices, and may not play in other DVD devices, including recorders and PC drives. What is MOD media? MOD means manufatured on demand. The disc is created after the customer orders and comes on a DVD-R. DVD-Rs look like the discs you're used to and offer the same audio and image quality. This recordable media is used to manufacture titles on demand, as fully authorized by the content provider. Each disc comes fully packaged, with artwork, in a standard Amaray case for DVD, although for reissued products the artwork may differ from the original. By eliminating inventory, waste, and inefficiencies in the distribution system, on-demand manufacturing provides the added benefit of helping preserve the environment.
