Joe,
Titles reside on the title track, not on the main video track. If you are not starting out on the main track with some kind of "leader" the first title will overlay on the first video clip(s) on the main video track.
Go up to the light grey media bar and click on the down arrowhead at the right. You will get a pulldown menu with media choices, select color boards. Now click on the black one and drag it down to the main video track on the timeline, and stretch it out for say about 8-10 seconds.
You should have nothing on the timeline at that point except a black clip. Go to the title room and pick the first title style and drag it down to the title track. Edit it to show what you want and then adjust it's length to less than the black clip on the main track.
Now add a few of your wedding video clips after the black clip and when you play it you should see black, then your title on black, then black followed by the first video clip.
Also what I said above about titles fading in and out is incorrect. In PowerDirector the only way I found to make titles fade in and out is to set them up as a separate video project, render them to a file and re-import the file so you can put that on the main video track. There you can apply the fade transitions.
Transitions do not work on the title track.
