PowerDirector only have 2 options: 1) Burn disk and 2) Create DVD Folder.
If you want to add extra folders to your DVD production like original photos or videos, the only way is to “create a dvd folder” and use another program to burn the DVD in a complicate form.
Is easiest if PowerDirector have a 3rd option to create the DVD ISO file and the use a conventional ISO software o add the folders like other many DVD authoring programs have.
