My main 'movie' starts out with a black frame. How can I pick a thumbnail pic to assign to the menu? The other 'movies' all begin with a normal frame and I don't have any problems with the thumbnail they show. Sorry if this is a dumb question.
There should be a filmstrip/timeline view of the media at the bottom of the screen (don't quite remember how to navigate there, don't have DVDA handy at the moment). Below that there is a toolbar - there's a small blue button that sets the thumbnail to the current cursor position. So just click on the timeline where you want the thumbnail to be, then click the blue button.
Got it in front of me now. You can also set the thumbnail position by clicking on the link in the menu, and switching to the "Object" tab over on the right. There's a "Thumbnail start time" with a slider, near the top.
It's me again. I tried your first suggestion and I selected the frame I wanted for the thumbnail just fine. But on the preview screen, as I tested the final creation prior to burning, I could not select that particular movie. I would click on tht thumbnail and nothing would happen. The other thumbs worked fine. After fooling around with the 'in/ out' points, I did manage to get the thumbnail to work but only as a chapter point. I could not get the movie to play from the beginning. Any idea on what I have done wrong?
