Dear All I am trying to play a video dvd but I get the following errors: with kaffeine, "The source can't be read. Maybe you don't have enough rights for this, or source doesn't contain data (e.g: not disc in drive). (Error reading NAV packet.)"; and with totem, "The source seems encrypted, and can't be read. Are you trying to play an encrypted DVD without libdvdcss?". However, I have libdvdcss installed. Any ideas? Paul
