I am using iDVD 09 and I have archived a project on an external drive. When I open the project archive, a window pops up saying some assets have been changed and it asks if I want to update. If I choose update, my chapters are screwed link and the menu always links to a wrong chapter. If I choose cancel, the chapters are ok but as soon as I want to burn a disc, the same window pops up. Does anyone has this problem? I am fairly new to iDVD so I could be missing something obvious. Thanks!
