Hi I did get the essential codecs package installed by following the procedure from another related message here; however, I cannot install anything using Yast it seems. In su mode I click on the .rpm and then say install then after 2 secs I receive a popup saying "Installation source not refreshed" I then have to click that box 6 or 7 times then it continues to where I think the listing of the files for installation shoulb be displayed as well as the dependencies, etc.. it is blank with zero entries then I say accept and them immediate finished popup with nothing installed. ???
Try installing "win32-codecs" or something similar if you want to get mplayer going. For the Kaffeine route, make sure that you reinstall xine-engine
