As there are questions about the legality of libdvdcss2, ubuntu cannot redistribute it.  It's not too tough to install though. Load this link and go to the section headed "Install libdvdcss2 and w32 video codecs in Ubuntu 8.04 (Hardy Heron)" and all should become a little clearer. <a href="http://www.ubuntugeek.com/install-mplayer-and-multimedia-codecs-libdvdcss2w32codecsw64codecs-in-ubuntu-804-hardy-heron.html" target="_blank">http://www.ubuntugeek.com/install-mplayer-and-multimedia-codecs-libdvdcss2w32codecsw64codecs-in-ubuntu-804-hardy-heron.html</a> Gavin -- edubuntu-users mailing list <a href="mailto:edubuntu-users@lists.ubuntu.com">edubuntu-users@lists.ubuntu.com</a> Modify settings or unsubscribe at: <a href="https://lists.ubuntu.com/mailman/listinfo/edubuntu-users" target="_blank">https://lists.ubuntu.com/mailman/listinfo/edubuntu-users</a> </blockquote></div> </div>
