Projects which I created in iMovie version 4 give me a warning message when I open them in version 5 or 6. The warning says that if I proceed, I will not be able to edit/open the project again in the original software. This could be a factor in the problem Richard is having. It may be necessary to have the same version of iMovie on both machines. Can versions 5 and 6 swap project files back and forth?
