Some Internet sites are showing video not using flash. They show .wmv stream. By default in Linux if you will open that site in Opera nothing will happen. But there is solution to this problem - we need to install mplayer plug-in.

To install Linux mplayer plug-in for Opera you should search for package mplayerplug-in.

I have found it using http://rpm.pbone.net here (I have RHEL 5.2 client)

After you install it

you may notice that it will install all the plug-ins to mozilla directory. That's why we need to copy them (or like in this example make symbolic links) to the Opera plug-in directory

Also we should make libxpcom.so available to all applications. Try to locate it and copy (or make a symbolic link of it) to /usr/lib directory .

and then just restart opera. Now you can watch windows online streams in Linux too.
