double-layer disc A recordable disc format that you can burn a dual-layer project to.
Because it has the same capacity as a dual-layer disc, it is able to use the dual-layer settings
in your project to place the break point, making it possible to test the project before
sending it to the replicator. See also
dual-layer disc .
double-sided disc A DVD with content on both sides of the disc. Most DVD players require
you to turn the disc over to play the second side. Each side can be single- or dual-layer.

drop frame timecode Timecode that represents the actual time duration of NTSC at
29.97 frames per second (fps). To achieve this accuracy in numbering the frames, two
frame numbers are dropped every minute on the minute, except for the tenth minute.

drop zone An element you can add to a menus background. You can assign a still image
or moving video asset to the drop zone. You can size, position, and rotate the drop zone.
When you build the title, the drop zone is merged with the background. Drop zones
cannot be linked to other elements in the project.
dual-layer disc A DVD with two layers on a single disc side, almost doubling a single-layer
disc’s capacity. While you can burn a dual-layer project on a double-layer drive, they are
most often created by a replication facility. See also
double-layer disc , double-sided disc ,
opposite track path (OTP) , parallel track path (PTP) .
duplication facility When you need to create multiple copies of a DVD, and the disc fits
on a standard DVD-R and requires no special high-end features such as copy protection,
you can use a duplication facility. The duplication process creates DVD-R copies from a
DVD-R that you burn on your system; they can automate the process and add professional
labels. See also
