DVD DUPLICATION This method is the one with which most people are familiar. DVD duplication involves taking a blank, recordable disc (DVDR or CDR) and burning the information onto it with a laser. Most of us have done this using a CD burner on our home computers. This method is typically used for smaller runs of 100 to 300 units.
DVD REPLICATION The DVD replication method is typically used for high volumes of 500 discs or more. It involves creating a glass master. That master is then used to press DVDs and CDs. These discs are essentially molded from scratch and created with the information already on them.
