Don't send to idvd from imovie. Use Share/Media Browser. I can then select publish and select the highest setting that I can. After its saved then I run idvd and then bring my movie in using media browser. This is the only way that I have found to eliminate the awful and jaggies. I usually do first burn to dvd-rw as a test burn which I then check out my dvd as I usually miss something. Hope this works for you. Bob
