From your reply, I am concluding that our exchange has been too difficult for you. So I will not be bothering further with this. Instead, I am contacting Corel directly to see if this can be resolved. You state that I am complicating what is very simple. You might be right. But I thought the simple part would be to just import my video file into Toast, add chapter markers, and then burn a disc. From what you have advised, I might be mistaken. If so, then I will hope that Corel will clear this up. Frankly, the path I have taken, based on your suggestions, is much more complicated than what I had expected. You are right, of course, it is difficult trying to give instructions in this way. That is why I tried to be as specific as I could about what was happening. It might be that this is not helpful. But, since we cannot have a person-to-person call on this topic, I don't know what else to try. Again, thank you for the effort you have made.
"I chose this option: H.264 for Blu-ray. " Why you choose? Once you clic on create BD, it is automatically selected everything by default! The file coming out of FCPX is already ready.
more look at the bottom line: during authoring your BD it was not able to create the menu. BDs require menu, like DVDs. To create a basic menu: this operation is available in compressor, by clicking on the bar "selected golden clips 5" a window on the right side should appear.
it is very difficult to give instructions by this way, but you have not to interpret: by interpreting, and so, changing things, you complicate what is very simple. Please, follow the help instructions, in the suitable menu.
