DDP (Data Description Protocol) is the preferred (and more reliable) format for submitting DVD-Video and DVD-ROM masters. This format does not add additional compression and in the case of DVD-Video provides a method of control over layer break location, region code, and copy protection. These must be formatted as DDP 2.0 or DDP 2.1. Upload a Layer0 folder for DVD-5s and in addition a Layer1 folder for DVD-9s.
