Hi, CliffG1!
It's quite easy to do what you're trying to do, I'll take you through the process, step-by-step. This, of course assumes you're not using any more than one video track(Dideo Track 1 - master track).
1) Using a colour board(which can be found by clicking where it says "Media Content", choose the black colour and drop it on the time line, might be an idea to set it at 10 seconds rather than 5, gives the viewer a bit more time to read the captions. Add your first clip, which will form the first "chapter" of your video.
2) Adding the "Title", click on the 'T' to enter the "Title Room", probably the default template will suffice for this excercise, Drop this onto the Title Track(or, as I've found in PD14, you can also use the Video Track 2 as a title track), click on the "My Title" in the timeline and type in your text(you might want to play around a bit with the layout of the text - but that's for later experimentation, we'll keep it simple for now).
Repeat steps 1 and 2 for the subsequent two chapters. Okay, once you've done that, now it's time to add the chapter points.
3) For this part of the process, go to the "Chapter Room" second-from-bottom, down left side of screen, hover your cursor over each icon there and that will tell you what each icon represents. On entering the Chapter Room, the first chapter is automatically added, but for this purpose, well be using "Manual Chapter Settings". Move the scrubber to the start of your second chapter, click on "C+", this will add the second chapter(the first was automatically inserted), now move the scrubber to the start of your third chapter and click again on the C+. Chapters are now added. Process complete!
If you intend to burn a disc from this, just go straight to "Create Disc". Follow the prompts and you'll have a DVD of your baseball match. When you've done this a few times, you may want to start experimenting with title fonts and effects, but that's for you to play around with later. For now I've kept it simple and straight-forward.
Cheers!
Neil.
