I was previously running Leopard with iPhoto '08. With this setup all .mov format movies that I took with my digital camera imported into iPhoto along with the pictures. They showed up in thumbnail view along with the pictures and I could launch the movies in Quicktime by double-clicking on the movie thumbnail in iPhoto. After upgrading to Snow Leopard (but still using iPhoto '08) the video thumbnails still show up, but double-clicking on them does nothing. Double-clicking on image thumbnails still opens the image as normal. I can still view the movies by right-clicking, selecting "show file," and then double-clicking on the movie thumbnail in Finder. I'd like the get the view movies from iPhoto functionality working again. Any ideas?
