Your video appears to have interlacing encoded by the source recorder. You can use HandBrake to remove interlacing while re-encoding. Aperture, btw, is photo editing and management software. It may play video, but there are players that are far better suited to video, such as QuickTime, or VLC. VLC, btw, is a defacto standard, and usually the answer to the question: "what will play this odd video format I can't seem to view with any decoder I've tried?" VLC has streaming and encoding functions as well. Final Cut Pro will of course play videos, but it is a video editing suite first, not "also," which means it is rather heavy amount of software for such a light task as playing video. You seemed to have answered your own question, but I thought I'd give you better confidence in your own answers.
