The transparencies are only a general roadmap of where you're going. You'll get lost if all you write down is what's on them. If the transparencies confuse you or are not helpful, ignore them for a day or two. See what happens to your note-taking if you just focus on what I'm saying.
More notes are better than less, even if the material sounds simple and common-sensical.
Review your notes later on in the day, and add anything and everything you can remember, even if it sounds trivial. If all you have is words and phrases, try linking them together in some coherent fashion. That what I strive to do in lecture. If there is something in your notes that makes no sense, email me with a question. The reading are best taken in small doses.
