Whenever I export from iMovie 4 to DV or full-size MPEG 4, the results are stretched horizontally. I've attached a screenshot showing the home movie with correct proportions playing in the foreground within iMovie and the exported result playing in quicktime in the background. You can see how my son's head is stretched. Is there any way to prevent this? If I export to 320x240 the proportions are somehow maintained. However, the grandparents like to see this stuff as large as possible. Thanks for any help.
