Quicktime movies are not displaying on the catalogue pages of the Science Photo Library website - one url below - but they are displaying on their demo movie pages. We're running Firefox 3.6.6 on XP Pro SP2 with the QT 7.6.6 plugin. The Library have tried this but say it's working for them; we have two machines here that can't see these catalogue movies. When clicking one of the icons to launch a preview movie, the QT either shows a question mark, but which is unclickable, or is white. In the latter case you can click the playhead, but it doesn't start the movie. Also, if you right click these, you get the options you would see if you don't have QT Pro installed, ie. the Save options have 'Pro' in front of them. We do have Pro licenses. We also have the VLC player and plugin installed. Disabling that in Firefox makes no difference though. Thanks.
