I have a 2011 Macbook Pro and can't believe how difficult Apple makes it to write a series of Youtube mp4 clips to DVD to watch via a DVD player on a TV. iMovie is truly the worst piece of Apple software I have ever encountered. I loaded all the clips on to a new iMovie project. The process/conversion took several hours: far longer than the cumulative clips themselves. I presume that was converting the mp4s into avi files? I then clicked 'Finalize project' ... but nothing happens. Now I understand I have to select iDVD to write to disc ... but iDVD is greyed-out under 'Share', even if I open iDVD separately! There doesn't seem to be any way to save the project anywhere, let alone write it to DVD. How do I write my project to disk? Thanks.
