There are quite a few ways to achieve DVD Duplication.
The first is the easiest method, which is to use Apples built in DVD Burning facilities. You can take the contents of any DVD and store them to your Hard drive and then create a new DVD template, copying across the data.
Obviously this doesn’t help if you are duplicating DVDs which aren’t strictly data based. For this you will need 3rd party software and I recommend a program like Toast.
Toast has easy wizards for you to follow. It will allow you to create new DVDs, duplicate DVDs using 2 DVD burners or using 1 burner and your hard drive.
It’s not free, but it is generally regarded as the best solution for any general burning task and can also carry out the more advanced and complication burning such as video encoding.
You can also contact other businesses which specialize in duplicating and replicating your CDs and DVDs. For large duplications such as music band releases and software releases, using a company to sort out the problem will most likely be less hassle and will acheive a more professional result. There is a lot of competition in this market so keep your eyes open for the good deals and you will find yourself inundated with duplicated DVDs!
