How do I write to DVD a movie from IMovie?
iMac, Mac OS X (10.6.8)
Your comment is in the iMovie for iOS section, but I'm going to guess that you are trying to burn the DVD from a Mac and not from a mobile device.
iMovie '11 (Version 9.0) working with iDVD was pretty straightforward, but things changed when iMovie was updated and iDVD was dropped. Which version of iMovie are you using, and do you have a copy of iDVD on your computer? That will help people reply and get you to the right section.
This page also looks very useful if you do not have iDVD.
