I have a similiar question. I made a movie in iMovie, exported it to iDVD, burned it to a DVD, then lost the original iMovie file. Is there a way to import it back into iMovie?
I've made a Project and exported it as .avi but the quality got very poor. I'd like to get the movie from iMovie and make a DVD with iDVD, so what would be the best way (talking about quality of images) to export it?
