It sounds like the program is having difficulty scrolling the text as transparent over the background.
Tip: Make a new project with just the scrolling text on say a bright blue color board background.
Produce it as a video.
Does it scroll OK ?
Now change the project to have your desired image as the 1st track and place the movie you just produced as a PIP and make the chroma-key be the bright blue so that the text appears transparently over your background image.
Produce this movie
Does it play perfectly?
If so append this movie to the main slideshow and get rid of the scrolling titles you had originally.
The reason for the jumping may be unclear but possibly lack of memory after doing the main DVD.
By creating iit seperately you avoid that problem since it does not need to process the titles.
