My Movie Factory is working!

But I have one more question, which is important to me. According to Doug on page 9 of this thread, "It does appear to let you create a DVD with NO MENU, so that the title just starts playing...when you insert the disk into the DVD player... The new DMF 2010 which is part of X3 has the capability to force the titles to play before the menu comes up... "
That is exactly what I want to do, but I can't see where that option is.
I made a video (actually an audio slide show with cello background and narrative clips) in VS X3, rendered it into an MPEG video file, and would like to have it run automatically on either PC or Mac without menus. It is only about 5 minutes long, and will be the only thing on the disk (unless I am allowed to put PDF's on as well and still have it start automatically).
When I burned the video file onto a DVD, using my regular disk burner since I wanted to avoid menus, it worked well on my own and other PCs if I clicked on the file, but would not open on a Mac; and when I tried putting it in the DVD player attached to our (old) TV, the picture was fine but there was no sound. Can I assume that these problems are because I didn't actually burn it via a video burner such as DMF?
If I should be putting this post in the Movie Factory forum I apologize and hope you will move it to the right place, but in view of Doug's comment and the SE version, I thought this might be best. I do hope I'm not being negligent again!
