+Subject: [PATCH] Adds a function to create a dpu of a dvdnav handle
+
+This adds a function to create a duplicate of a dvdnav handle and it's
+state. This allows you to recursively move through the handle. HandBrake
+uses these functions to do recursive automated search of the menus for
+something that looks like the main feature.
