DVD-R masters are perfect for most duplication jobs, for both our Short Run / Fast Turnaround Service and our 'pressed' DVD Replication service for longer runs. Typically a DVD-R master is perfect for DVD 5 and DVD 9 jobs - single and dual layer.

These days it's easy to create a DVD master using freely available software and most computers shipping with a DVD Writer. However we'd suggest it's good practice to test your master on as many DVD players as you can.

For peace of mind we are happy to supply a 'pre production' sample for you to test prior to duplication when your order is for DVD-Rs.

DVD-RAM masters are not acceptable.
