I have had a go at setting this up and it complains saying it won't play encrypted DVDs even with libdvdcss installed.
Just been looking at my notes- I found that although the make install went 'OK' it HADN'T copied the files to /usr/lib/ (on Debian). Perhaps check that.
If not, run xine from the terminal and give us some error messages!
--in fact, I'm just rebuilding my machine after my HD crash. I need to add dvd support...
--back! I needed to: 1.download libdvdcss-0.0.3-ogle3 from: http://cambuca.ldhs.cetuc.puc-rio.br/~jcm/skyblade/XINE-0.9.06/source.TAR.BZ... 2.apt-get install ogle-mmx ogle-gui 3.bunzip2 libdvdcss; tar -xvf libdvdcss ; ./configure ; make ; make install 4. cd libdvdcss/lib/ 5. cp * /usr/lib 6. chmod 666 /dev/hdc 7. mount /cdrom 8. open ogle, open /cdrom and watch Crounching Tiger.
Unfortunately, xine still doesn't play them. Maybe you need to put the .so 's elsewhere.
