When I'm in the title editing window and press the 'play' button, the title does what I want and appears as expected over the section of the video clip it overlaps on the timeline).
However, when I exit the title editor window and view what should be the combination of the clip and titles (clip and its audio in track 1, added titles in the "T" track), they don't appear when pressing the preview play button. Only the video clip plays. The timeline marker runs over them, including the one that extends beyond the end of the video clip, but they don't appear in the preview viewer window, or in the final product burned to disk.
Is this a bug, or am I doing something wrong?
