For this tutorial we will be burning an iPhoto slideshow we created in an earlier tutorial; however, you can use any video clip of your choice.
Launch iDVD by selecting its icon in the dock.
Click to select OneStep DVD from Movie... from the File menu.
Select the video you would like to use and click the Import button.
You will now be asked to insert a recordable DVD. Please do so.
iDVD will now prepare the DVD, process the movie, and burn it.
You will be informed when your DVD has finished burning successfully.
