You need libdvdcss which will then enable you to play DVDs just fine you will find it easier to install if you first get Kpackage installed (part of kdeutils I believe - just search through the packages for one that references kpackage) then download and open http://download.videolan.org/pub/lib...2.9-1.i386.rpm with it. There is a page on the web somewhere with instructions about this and adding alternate installation sources - I will try to find it for you to save me typing it.

Wahoi that didn't take long here you are
