+<h2><a name="menu"/>Menu features</h2>
+
+<p>The menu features are handled like a <em>chapter codec</em>. That means each codec has a type, some private data and some data in the chapters.</p>
+
+<p>The type of the menu system is defined by the EditionManaged parameter. For now only 2 values are supported : 0 no menu, 1 menu borrowed from the DVD. The private data depend on the type of menu system (stored in EditionManagedPrivate), idem for the data in the chapters (stored in ChapProcessCommand).</p>
+
+<h3><a name="dvd"/>DVD menu</h3>
+
+<p>This is the case when EditionManaged = 1. Each level of a chapter corresponds to a logical level in the DVD system. This DVD hierarchy is as follows:</p>
