A CAVS SuperCDG disc is simply a DVD (or CD, though less common due to the limited size) that contains a single SuperCDG library. Since SuperCDG library data files are not of a fixed size (they grow as you add new tracks to the library) you should be careful when building the library to keep the total size of the data files within the space limits of the media you intend to burn onto. It is good practice to hold the data file sizes slightly below 1GB (more precisely, at a maximum of 1018MB each) to allow for four data files on a single-layer DVD and eight data files on a dual-layer DVD. If you need to fill the DVD to its maximum capacity you can start by adding about 200 tracks per data file (i.e. 800 tracks for a single-layer DVD and 1600 tracks for a dual-layer DVD) and then add more tracks in smaller chunks while monitoring the total size of the SuperCDG library during the process.
See the topic SuperCDG libraries for details on how to create a SuperCDG library and for more information regarding number of data files and tracks.
When you create a SuperCDG library for use with SuperCDG players or software you must make sure you name the library CVMD. When the library is finished simply use a burning software of your choice and burn the data files (CVMD0001.DAT, CVMD0002.DAT, etc.) onto the DVD in a folder named CAVS_MCG. When finished the SuperCDG disc should contain one folder, CAVS_MCG, that contains the library data files.
It is possible to create self-loading SuperCDG discs that auto-runs an embedded player when inserted into a computer. Read more on this topic at Create a self-loading SuperCDG DVD.
