In PP 2007, I have started a new presentation. I have never inserted a movie before into a slide. My first two slides have movie inserted, which I set to start automatically.

When I hit F5 to start, the movie starts then has a frame of black flash for a tenth of second then continues. What am I doing wrong? Movie is short avi file. I have reviewed these files with three different videos editors that I have and there is no black frame or any break in the movie.

I indicated when inserted that the movies started automatically. Yet when I start by F5, the first movie runs and stops and the second movie wont start by itself unless I click. Thanks.
