As I have written in the previous article, to make Opera play on-line streams that require Windows Media Player on Linux, you need to install mplayerplug-in. Following steps are Fedora Core 10 related.

The latest version of mplayerplug-in for Fedora 10 can be found here - http://atrpms.net/dist/f10/mplayerplug-in/. But if you will download this package separately it will require many dependencies. So I suggest to create file /etc/yum.repos.d/atrpms.repo

And after you install mplayer plug-in

Add following line to /etc/yum.repos.d/atrpms.repo to deactivate this repo:

After this you should copy installed libs to Opera lib directory and restart Opera, as it is written in my previous article.
