Playing commercial DVDs
Go into Yast and search for and uninstall 'xine' if it is
installed.
Then goto
http://cambuca.ldhs.cetuc.puc-rio.br/xine and
download and install the .rpm files for the following
1) w32codec-0.52-1.i386.rpm
2) libxine1-1.0.1cvs-050610.i686.rpm (or i586)
3) xine-ui-0.99.3cvs-050610.i586.rpm
4) libdvdcss-1.2.8-2.network.i386.rpm
You may also be able to find these files on the Packman
servers.
For legal reasons Suse cannot include the files which
enable you to play encrypted DVDs, so you have to install
them yourself.
For astronomy go into Yast->software management and search
for Celestia.
