Utter Despair

I've been editing video with Final Cut Pro for 9 years now, yes that's NINE YEARS. Yet today I'm wrestling with a problem that brings me to the brink of complete, throw-up-my-hands frustration. Absolute utter despair that makes me want to just give up being a filmmaker completely, or at least being an editor.

It's pretty much too complicated to describe here quickly and not have someone mistake it for a stupid mistake.  Trust me, it's not a stupid mistake.  I'm not an idiot, and, like i think i mentioned, I've been using FCP for NINE YEARS.  Trust me when I say this is a completely new and weird fuck-up that is a total mystery and that you would probably have no idea how to solve either unless you have as much intelligence and experience with this software as I do. 

In other words, I'm not posting this to ask for help. I'm just screaming my frustration.   Thank you, Apple, for once again leading me to believe that I could trust you and your products. sigh.
