well what you installed isn't the xine libraries or the player, but just the win32 codecs. but to see if you have xine installed, just open up a shell terminal and type the command "xine" with no quotes. if you get an error, you probably don't have xine installed. in that case, go here,
http://xinehq.de/index.php/releases, and download/install xine-lib and xine-ui. but, iirc, suse should have xine installed.
