Toast 8's Help file states: "To add an iMovie HD project, first save your project and quit iMovie. Then add the saved iMovie project file into the Content Area. You do not need to do any special export formatting in iMovie prior to adding the project to Toast."
I did the above, checked all the settings, made sure I had room on the DVD (less than half the space needed) and hit record. At that point I got the error message: CD-ROM XA or Audio tracks cannot be written to DVD.
Does anyone have any idea what the problem could be?
I'm replying to my own post because, as I've seen so often on these forums, as soon as I posted the message and returned to Toast, I saw immediately what the problem was. In case others have the same problem I thought I'd just post the solution here.
I had inadvertently chosen the Super Video CD format. As soon as I switched to DVD-Video format the error message went away and the disk is happily burning as I type.
Sorry to bother you all!
