Thanks to Michael R, Fabian I, rrsounds and Robert R for your suggestions on problem of finding and trashing partly encoded iDVD from iMovie. I had trashed my project "Name of project.dvdproj" as well as one called "My Great DVD.dvdproj" which the program puts in -- to no avail. When I start a new DVD from scratch, the customize status in iDVD 3 still says 4.17 GB of 4.40 GB encoded. Project size 56.50 min. I also checked on my startup disk space. I clicked on OSX in finder and then on any other such as Applications. At the top of the window it reported 712.4 MB available which should have been plenty of space for encoding. My project is on the outside firewire HD which is a 176 GB La Cie. Is my arithmetic right? 4.40 Gb minus 4.17 Gb = 0.23 Gb, which is 230 MB which should fit in the 712.4 MB left on the OS X startup HD. I guess I need to trash the iDVD application and reinstall from the Jaguar disk if that is possible without installing iMovie 3, iPhoto 2 etc. Let me know on this. Thanks in advance
