A money-saving word of advice: DVD duplication and DVD-ROM replication sound similar, but there is an important distinction. The burn-and-print duplication process is way to go for short runs--usually fewer than 1,000 copies. However, if you are a major player and need more than 1,000 copies duplication will end up being an expensive choice. DVD-ROM replication is a more cost effective method of producing large quantities. The company you select will produce a "master" disc, then "press" copies that are perfect duplicates of your original.

Another tip: DVDs are not immortal. The thin aluminum layer that reflects light of player's laser, is susceptible to oxidation which causes discs to "rot". Never use off-the-shelf markers or ball point pens to write on discs or labels. Most markers contain chemicals which create oxidation, allows air to penetrate aluminum, which is eaten up much like iron rusts in open air. Special pens are now sold which are made specifically for writing on media.

Whether you choose to purchase your own DVD duplication system or "farm out" your project to a professional duplication service be sure to do some comparison shopping. No matter what your project or how many copies you need, there is precise product or service out there for you.
