Which version of the OpenSuse you are using and is your system 32-bit or 64-bit architecture?
What is the desktop environment you have installed, KDE or GNOME?
In YaST, go to Software section. There is an entry for configuring the Software Source/Repositories. Open that, then in the Software Sources/Repository window, select, Community Repositories. Click Next. You will see a list of software repositories. In that select, Packman repository. Click Next. It will download the repo data about software packages.
Once done, install the W32Codecs package using the software centre or in terminal execute "zypper in w32codecs-all" without the quotes and as a root/admin user.
You can also install VLC media player which plays most of the formats.
