Duh... you know, if you ask the wrong question, you'll never get your problem solved. And in this instance, I just didn't change paradigms. What I realized late last night was that I needed to delete what I was unhappy with, go back to the original clip, isolate the correct segment, and then "add on sequence."
Dumb as I feel, I hope this helps some other newbie. Someday.
Thanks for trying to help that newbie.
