I heard that in order to play dvds on Linux is to download a plugin for it called libdvdcss. Well i downloaded the RPM but when I try to install it, it says that its already installed. I cant find it anywhere on my computer however. I tried to remove it with 'rpm -e [filename]' and it says that it has not been installed. So, if i try to install it, it tells me that its already installed but if i try to erase it, it tells me the opposite. Has anyone else had this problem?
