I have a site with lots of video, that is played with windows media player. It should work online and offline (from CD). When users user site offline they can't install plugins (because they do not have internet access), so I wrote an offline pluginpage for them with already downloaded plugins.
I use <embeded pluginspage="file://somepathtoplaginpage"> but it doesn't work. The browser still tries to install plugin from internet.
Do not know if it really a bug or a feature, but I need to fix it.
