I'm new to linux, so I'm still learning a whole lot. I've looked around, and haven't found the solution to my question, so I figured I'd post it.

I have fedora core 1, and I installed mplayer. It worked fine, then I installed the mplayer-plugin to stream video. I am using Mozilla v1.6. When I try to view any video type, it brings up a screen that says Mplayer plug in, and downloads the video. However it never opens mplayer and plays the file. I've tried opening mplayer, and then clicking on the videos, but it won't work. I don't even know how to un-install the plug in to get back to the original mplayer .

any suggestions?

Check out how Mozilla is set up to react to .avi, .mpg (etc) files. Go to edit/preferences/helper applications and have a look. So if you are trying to stream .avi's, add a new type, MIME: avi video, and extention: avi, and choose 'open it with' /usr/local/bin/mplayer or where ever your mplayer bin is. Do 'which mplayer' to find out.

Oh yea: Welcome to Linux

If you added the mplayerplugin with an rpm, you can remove it the same way. Replace it with mozplugger. The two conflict anyways, but mozplugger seems to work with streams and stuff.

mplayerplug-in works well with mozilla 1.X
check you .mplayer/config file (drivers,etc...), check you've got all codecs installed(win32 codecs), check mozilla aboutlugins page.
