mplayerplug-in-2.45-rhl9.i386.rpm successfully installed, but it's neither listed in "about plugins" nor does it work.
I'm using RHL8.0, Mozilla 1.6, Mplayer1.0pre3. And I've placed mplayerplug-in.so in the plugins directory. PLZ help me!
did you also copy the mplayerplug-in.xpt into the mozilla/components directory?
Since you have RedHat 8 and Mozilla 1.6 and I'm not sure where you got Mozilla 1.6 you need to do the following
cp /usr/lib/mozilla/plugins/mplayerplug-in.so ~/.mozilla/plugins
cp /usr/lib/mozilla/components/mplayerplug-in.xpt ~/.mozilla/plugins
See if that works.
You also need to delete your $HOME/.mozilla/pluginreg.dat whenever you change or add anything plug-in related. This will make Mozilla reread its registry. (As I understand it, this is required also if you change your "mplayerplug-in.conf" file as well. I would guess it also applies to "mplayerplug-in.types" too.)
