I've often read on this site of other people's of problems after applying Software Update, but never had one myself. So this is a first. After updating to QuickTime 7.1.5, my Kodak EasyShare application would quit whenever I tried to transfer, play or edit a video file. It would do this without generating a Crash Report, or any log file that I could find, which initially made it difficult to pinpoint where the problem was. I initially thought it was related to a new OS X user account I created, coincidentally around the same time the QT update came out. Then I uninstalled and reinstalled the EasyShare software, to no avail. It was only when I reverted to QT 7.1.3 (using the instructions on this site: http://www.macfixit.com/article.php?story=2007031310092798) that the problem went away. To double check that the original problem was not due to an incomplete installation of QuickTime 7.1.5, I did a "forced install" using Pacifist (http://www.macfixit.com/article.php?story=20070313101411459). Hey presto, the problem returned and the app would quit again every time. I don't know enough to figure out whether this problem is limited to my version of the operating system (OS X 10.3.9), or a quirk of my particular machine, though I doubt it. The moral of the story is: Don't upgrade to QuickTime 7.1.5 if you're running Kodak EasyShare. I'm not overly confident that Apple will make fixes in future to accommodate this relatively uncommon(?) competitor to iPhoto, and Kodak don't appear to devote great resources to their Mac ports, but we can always hope that the conflict might possibly be resolved in future releases from one or other party.
