* The locations and dimensions of buttons are given to <tt>spumux</tt>. <tt>dvdauthor</tt> gets this information from the MPEG files generated by <tt>spumux</tt>. Also, buttons are referred to by user-specified names in both <tt>spumux</tt> and <tt>dvdauthor</tt>, even though DVD-Video doesn't support button names.
* <tt>spumux</tt> allows the specification of multiple graphic files, each potentially containing a different set of colours, even though DVD-Video subpictures only allow a maximum of 4 colours to be displayed at once from a maximum palette of 16 colours. <tt>spumux</tt> embeds information about the colours actually used, and <tt>dvdauthor</tt> collects this to correctly encode the generated subpicture pixels and build the complete palette.

<tt>dvdunauthor</tt> and <tt>spuunmux</tt> are very useful for trying to understand the structure of existing DVD-Video titles.

Additional useful information about DVDAuthor has been collected at the [DVDAuthor Wiki | http://nfs.shawnfumo.com/wiki/DVDAuthor/Overview].
['Q' DVD-Author | http://qdvdauthor.sf.net/] is a [GUI]-based tool to ease the job of [DVD] authoring. It can generate the [XML] files and command sequences necessary to drive the various CommandLine utilities in the <tt>dvdauthor</tt> suite.
<tt>qdvdauthor</tt> and the <tt>dvdauthor</tt> documentation examples make heavy use of the [MJPEG Tools | http://mjpeg.sourceforge.net/] package for generation of [MPEG] files and the like. However, all these operations can be performed just as readily with [FFmpeg].
