i have a new imac; and put my idvd onto it. I asked the computer to put a project onto the idvd. It took 3 minutes to load and then came back with wanting "themes" what is that? and my search found none. Thanks for any help. I have to burn about 12 dvd's. I download from camera onto imovie, and then go to Share-idvd. I know there are lots of problems with the new imac; and i bought it especially for making dvd's from imovie. I will look on my old computer to see if there is something called 'themes' that needs to be transferred.
