Excerpts from the DVDSP User Manual:
Building the Project
Once you have set the prebuild disc properties, you can build your project. Depending on the size of your project and the speed of your computer and disk drives, this process can take several hours to finish.
To build your project:
Do one of the following:
• ClickBuild in the toolbar.
• Press Option-Command-C.
Select the drive and folder to build to in the dialog that appears, then click Open.
The build process begins and a progress bar appears that shows the element names currently being compiled. If the selected folder already has a folder of the same type it is generating (VIDEO_TS or HVDVD_TS), see “Incremental Builds” for details on the dialog that appears.
The Build Files for SD Projects
Once the build for your SD project starts, DVD Studio Pro creates two folders at the location you specified: an AUDIO_TS folder and a VIDEO_TS folder. Additionally, a third folder, JACKET_P, is created if you have assigned a jacket picture graphic.
The AUDIO_TS folder is used by systems authoring DVD-Audio titles. To meet the DVD specification requirements, DVD Studio Pro creates the folder and leaves it empty. The empty folder is included in the format process.
This is NOT rocket science... It is simple and relatively fast. If you have a Mac that was built in the last decade it will take less than an hour for an 80-minute show.
good luck
