DVD Commands
The DVD navigation and playback commands are defined in a section of the DVD specification named Annex J, which is why the DirectShow documentation often refers to "Annex J commands." The names given in Annex J are not always very intuitive, however, so DirectShow uses names that may be easier to understand. Table 1 lists the Annex J commands and their DirectShow equivalents.
