Is purchasing Quicktime Pro worth it. I have a variety of video formats on my Mac, e.g.. MP4, MPEG and AVI. In fact the majority are AVI. I am a new switcher from PC and it looks like the purchase of QT Pro will allow me to convert the many videos to a format playable on my Mac. I also have an iphone which looks like its fully supported by the pro version. So the question is, is it worth paying the $30 or so to upgrade or would I be wasting my money ?
