After reading throught most of the discussions on Encore dealing with Layer Breaks [even though none seemed to directly addressed the issue I was having], it gave me an idea on what to try that ACTUALLY WORKED! [Yea!!!]
I reset all of my chapter marks from every 5 minutes to every 4 minutes which, I assume, gave Encore more choices on where to automatically place the layer break.
***A Reminder for others [just in case]: NEVER place chapter marks closer than 3 minutes apart or within 3 minutes of the end of your clip.
For some reason Encore does NOT [usualluy] like having its chapter marks crowded any closer together than that.
{God, I can't believe it was somethign as stupid as changing the chapter marks!} ::facepalm::
