What is the difference from a DVD copier, burner, and duplicator?
A DVD copier/duplicator copies directly from another DVD, creates 1:1 disk and is usually software based. A DVD Burner records data from a source such as your pc to a dvd disk A DVD recorder (or, colloquially, a DVD burner) is an optical disc recorder that records video onto blank writable DVD media. Such devices are available as either installable drives for computers or as standalone components for use in studios or home theater systems.
A DVD copier is a device that copies an existing DVD onto a blank DVD-rom. A duplicator does the same. Both of these functions are accomplished through the use of a DVD burner, which in addtion to “copying” DVDs can create original DVDs, ie a back up of all your digital pictures, or music collection.
