Only one problem with the Archive feature. My latest 54 minute movie created with iMovie with 22 chapters took up 13 GB as an iMovie folder. The .dvdproj file that iDVD saved was 3.96 GB and could not be used without the original iMovie folder present (movie project folder is on external drive and .dvdproj file will not open when external drive not mounted). When I made an iDVD archive, it took up over 26 GB!! Why is the archive 10GB more than the raw materials alone? Instead, I drug the iMovie project folder to the laptop hard drive where the .dvdproj file is. What is the purpose of an iDVD archive????
