Following the recommendations found here: http://cambuca.ldhs.cetuc.puc-rio.br/xine/, I was able to at least get Xine installed and am using that instead of Kaffeine. I now have full DVD playback although it skips and I assume that has to do with the DMA settings for the drive. It is set to DMA33 which being an old system is all it's capable of, but it still skips. I can live with that for now.
