Need 'MIME Plug-in? apparently...

Question

Hi, get the following message when trying to click on a QT movie (so far just on apples site - i can view video previews in itunes). It wants me to dl and install qt even though its already on my computer (i have latest 7.1.3).
The page “Apple - Trailers - Dreamgirls - Teaser 1” has content of MIME type “video/quicktime”, but you don’t have a plug-in installed for this MIME type. A plug-in should be available on this page:
http://www.apple.com/quicktime/download/
ive tried a couple of times to re-install but to no success

Hi
if you've used the "installed plug-ins" command from Safari's Help menu & see no mention of QT, then No, of course that isn't normal.
You should see a section headed-
QuickTime Plug-in 7.x.x
The QuickTime Plugin allows you to view a wide variety of multimedia content in web pages. For more information, visit the QuickTime Web site. — from file “QuickTime Plugin.plugin”.
then a long list of mime types that the plugin handles.
So - assuming you don't see that, either the plugin is missing for some reason or there's a conflict that doesn't allow it to load.
Take a look in your Home/Library/Internet Plug-Ins folder - if you see any QT plugin or webplugin file there, remove them to the desktop or trash.
Now look in HD/Library/Internet Plug-Ins/ amongst other files, this should contain QuickTime Plugin.plugin
IF you found a QT plugin in the Home account plugins folder & have removed it, you should quit any browsers & re-open them - hopefully you will now have QT functioning.
IF you have no file 'QuickTime Plugin.plugin' then it seems something went wrong with the installation or a recent update.
Anyway, let us know what you find out.
