Apature won't play video and freezes.
Hello, I've got a problem with Aperture 3. Every time I try to open a certain video in a slide show the beach ball appears and nothing happens. The video itself is not the probelm: It runs perfectly in another folder inside Aperture.
Also: whenever I try to start this particular slide show from a certain picture it starts somewhere else.
