what is gdm/xdm/smbfs and dvd's?

Hi everyone, I'm trying to set up my system and as I'm new to this some things are still a mystery... During boot I get messages that gdm and xdm failed while smbfs was skipper. What are they and does it matter? Secondly - could it be connected to the fact that i don't seem to be able to mount dvd's in suse - either kde or ximian (which I prefer). I thought i learned the tricks on mount but no success... xine also gives an error... thanks to everyone, j. __________________________________ Do you Yahoo!? SBC Yahoo!
