This is the final chapter in "Final DVD Won't Play." It appears the media I was burning to was too fast for my DVD players. That would explain why everything seemed to be going so well but they just wouldn't play. I friend of mine had run into a similar problem so I burned the project onto an older +R disk and it fired right up in my set-top player.
I have to say that I find it wrong that we would have to upgrade our players if we want to use newer, faster media. I'm sorry, it is just wrong!
