VSG:DVD:Linux

This tip is only intended for Linux users who can't play any DVD.
Maybe you don't have the libdvdcss package, which you need if you want to play DVDs with VLC. You can get the libdvdcss package at: http://linux.softpedia.com/get/Programming/Libraries/libdvdcss-165.shtml.
You can try to check about you have the access rights for your DVD player. You can open the chmod to edit the access rights →
write “# chmod 666/dev/dvd”. Where “/dev/dvd” depends on your DVD drive. To change this go to Setting → Preferences → Input/Codecs → General find “Default devices and see if your correct DVD drive path is entered in the “Default DVD” box.
