Replication and duplication are different methods of copying a disc. The main difference is that duplication is burning the disc and replication is molding the disc from a glass master. The results are the same: a copy is made. Usually the method to use is determined by the quantity and the timeframe the copies are needed.

Duplication – mainly for short run discs (<500) and faster turnaround time
Replication – higher minimum (>500), lower cost per disc and longer turnaround time

For example, a client who needs 100 discs will opt for duplication because the minimum for replication is 500 discs. A client who needs 2,000 discs in 3 days will also be doing duplication because the normal turnaround for replication is about 10-12 days.

The quality of the copies on replication and duplication are the same. However one thing we should point out: since duplication makes use of blank media for the burning, it is possible that certain (older) DVD players will have compatibility issues. The number of incompatible machines are minimal and should not be a concern. Another way to minimize the problem is to use high quality grade A media, which in general has higher success burn rate and is more compatible for DVD players.
