Re: adobe media encoder

background-knowledge:

adobe media encoder (and all other DVD-asset-encoder), creating so called elementary stream, that means audio and video are seperated.

within your authoring-process you can put more than one video or audio into your timeline (at one time).

that´s necessary to have different audio-tracks for multi-language DVD/BDs or maybe different cam-angles as a mixed/multi-angle DVD.

so you need to have elementary streams before authoring to multiplex them again, to get all this working.
