I am having really annoying problems with QuickTime 7. When I try and watch cetain movies that are embeded on sites, I get a faded QuickTime logo with a Question Mark on top. e.g. http://www.apple.com/ipod/ads/rollerskating/480.html But other pages work just fine: e.g. http://www.apple.com/trailers/wb/harry_potter/thegobletoffire/ Having read a suggestion on Apple's discussions page, I deleted a file called "QuickTime Plugin.webplugin" in the Internet-plugins folder, which kind of fixed the problem... but then created a new one. Now I don't get the Question Mark, I just get the QuickTime Logo until the movie has been fully downloaded, then I can watch it. It is no longer possible to watch a movie while it is being downloaded. Any help would be greately appreciated. I am using Mac OS X 10.4 (clean install). I have tried repairing permissions, and checking the disc, etc. I have tried installing the Operating System again. I have tried trashing the preferences for Safari and QuickTime.
