Movies with no appended cpxxxxxx IMDB id and poorly named files fail

Even though we have expanded the guessit approach, there still tend to be failures if the release group puts their name first... This is going to be a bit tricky, I just want to document it.

I suspect the only way we'll fully eliminate this error is when CP implements proper extra_script support where the ID is passed to the script.
