Hi, I am new to macs. I have, on my Mac Mini, managed to download a video from my camcorder and using iMovie (and Youtube tutorials) managed to create a movie complete with titles and transitions. How can I convert this movie to DVD format and burn it to an external DVD burner (that I have)? There does not seem to be a program on this mac that came with Mountain Lion? Youtube tutorials suggested clicking on share and then choosing iDVD but that choice is not there. Thanks in advance you all.
