I made a sweet montage in iMovie for an upcoming family event. It's about 11.5 minutes long and includes photos and video footage. I need to know the best way to save this as a movie since it will be shown on a big screen in a banquet hall (through a projector connected to a mac laptop). Can someone advise me on the best way to save this and burn it as a dvd? Should I just click iDVD and let it do it automatically or should i click export movie and then burn it to a dvd? Any suggestions and details on how to save it (widescreen vs regular) are greatly appreciated.
