Thanks for the help, but it was no help.
When I ran "sudo apt-get install libdvdcss libdvdread4 libdvdnav4", I got "Package libdvdcss is not available, but is referred to by another package...blah blah blah...is missing, has been obsolete or is only available from another source. E:Package libdvdcss has no installation canditate."
when I run "sudo apt-get update", I get may errors,..."Something wicked happened resolving 'packages.medibuntu.org...no address associated with that name.....". I get a pile of them near the end of the run.
How can I make sure my repos are set right, and how do I know they are set right?
Also, a newbie question....once you start KDE desktop, how do you get back? Just launch the script in the window at the top? Doesn't that leave KDE running?
