My next question and this seems like it should be simple. As I rip all my DVD's I want to store them on an external HD. How does this work with iTunes. I have a 2009 Mac Book Pro, with 113gb of music, and now 15gb of movies and that will grow very quickly. My internal HD is only 250 gb, and is rapidly getting very close to capacity. If I move all my movies to an external HD will iTunes just recognize that external when I plug it in, or are there steps I need to take to make sure it sees the files? I also have a TM and have read a few threads that suggest I could plug in my externals to it and have access to the files through streaming through the TM.
