Playing dvds, pclinuxos 2007
I am completely new to linux and have installed pclinuxos 2007 on a desktop to try. So far everything has gone fine and I'm impressed, other than I am unable to play dvds. I get error messages referring to the regional encoding regardless of which player I use, vlc, mplayer etc. I presume that I have to install other software to play dvds in my region(uk), but can somebody point me in the right direction?
