DVD 1 was simple to use. I can't find where the thumbnail is to show a part of the video you are to click on. I think it should have been left where it was...
You are trying to have animated clips act as the menu buttons right?
Starting a new menu based project, add your video clips to the main menu. They are now represented as buttons. Select the buttons you want to animate then follow bstros instructions:
On the right panel click on button properties. Then select Graphics. Then set "style" to "animated". The media the buttons link to will now play in the buttons window.
Sorry, just a joke but I'm not sure where the properties tab is.
Windows in DVDA can be moved around, but I believe that by default, the Properties one is on the right. Hitting Alt-8 twice should move it to the front of whatever stack it's in. (The first time closes it, the second time brings it back.
