EDIT Anyone know how to change the source from where it adds the next title. Mine has gone to some temp file location but would like it to automatically look in the folder I download to
If you are talking about AVStoDVD, it always remembers the last folder opened when importing a video. So, if you open a video in a particular folder, it should go back to it the next time you try to import something.
You can set the DVD Assets path in Preferences, and save current preferences as default, but the behavior to look in the last opened folder seems to take precedence.
