Slow DVD Playback on SuSE 9.2

Hello, I was trying to re-install xine because crypted dvds playback won't work on a 'standard' suse package. I uninstalled kaffeine, totem, libxine, xine & the other plugins, and i downloaded packages from packman. Now xine works and plays dvd but it's almost impossible to watch them: the playback is really slow, sometimes the dvd hangs and i've to wait seconds to see the images again. How can I fix it? Thanks
