Using Pre-Encoded Sources
Many other available tools, including software and hardware encoders, produce MPEG
streams. You can use any MPEG encoder you prefer, as long as it creates DVD-compliant
elementary streams. This means that the audio and video information is contained in
separate files (the streams).
Important:
DVD Studio Pro cannot use MPEG multiplexed System, Program, or Transport
streams for DVD projects.
See
About MPEG Video
for more information on DVD-compliant requirements.
