I am planning on replacing my 3G/15 with a 5G, but I have a concern that will drive my decision on 30 or 60. I keep all my music (currently 15GB) and photos (currently just under 3GB) on my laptop. Movies, I keep on my external. I was wondering if adding movies to the library will keep the movies in their current location on the external even though I have iTunes organize my music (and copy into iTunes when I add music). I called Apple Care to get the tech support side of things - they told me that I need QT Pro to add any movie to iTunes, and that if I add a movie to the iTunes library it will be added to my internal HD where the music is. Is that right and for home movies is iMovie or any free software able to make the conversion?
