Disk Description Protocol (DDP) is the preferred format in which DVD's are submitted to replication facilities in order to make thousands or even millions of copies. DDP format was originated by Doug Carson Associates (DCA), adopted by committee, and ended up in two flavors, DDP and CMF, which are essentially identical. (I guess fighting over turf?).

For standard definition DVD's, there are two versions:

DDP 2.0 DDP 2.1 or CMF 1.0

The vast majority of DVD's are submitted in DDP 2.0 format. The later version add two main features - specifying the region code directly in the DDPID file instead of requiring that the CONTROL.DAT file be in 2054-byte sector format, and a VOBTABLE file to specify which portions of the DVD are to be encrypted with CSS.

DDP 2.0 format is also known as "Plant Direct" by Sonic Solutions, the providers of Sonic Scenarist, Creator, Fusion, and other DVD authoring products.

For HD DVD, DDP 3.0 (also known as CMF 2.0) must be used. DDPAfterBurner does not support DDP 3.0 at this time, since so far replicators have not embraced DLT drives for HD. HDAfterEdit does support this format.

For Blu-ray, a flavor of DDP 3.0 is used, which will also be supported by HDAfterEdit.
