[Ubuntu] 解決無法播放已加密的DVD影片
最近播放DVD出現一則系統提示訊息： " Could not read DVD. This may be because the DVD is encrypted and a DVD decryption library is not installed. " 無法播放DVD，為讓Ubuntu順利播放DVD必須將缺乏的libdvdread4，libdvdcss函式庫安裝進電腦。解決方法如下： DVD播放函式庫安裝： Step1. 安裝 libdvdread4 $ sudo apt-get install libdvdread4 Step2. 接者安裝 libdvdcss $ sudo /usr/share/doc/libdvdread4/install-css.sh 參考： https://help.ubuntu.com/community/RestrictedFormats/PlayingDVDs http://askubuntu.com/questions/500/how-can-i-play-encrypted-dvd-movies
