无法挂载 DVD

我的操作系统是 ArchLinux，在一台旧的华硕笔记本电脑上运行。最近，我从商店挑选了一套 DVD 盒装，后来发现它们无法在我的电脑上播放。我以为 DVD 出了问题，于是我回到商店，令我惊讶的是，它们在商店的 DVD 播放机上播放时效果非常好。

我不记得过去几年播放过 DVD，但我确实遇到了一些特定地区 DVD 的问题，这已经是很久以前的事了。

通常，DVD 是由 Nautilus 自动安装的。我尝试使用以下命令安装设备mount：

localhost% sudo mount -t iso9660 /dev/sr0 ~/cdrom 
mount: /dev/sr0 is write-protected, mounting read-only
mount: no medium found on /dev/sr0

我认为问题很可能与硬件有关，但任何指示都会非常受欢迎。

命令的输出cd-drive位于粘贴箱。

更新#1：

以下是dvd*我的操作系统中存在的软件包：

extra/libdvdcss 1.2.13-3 [installed]
  Portable abstraction library for DVD decryption
extra/libdvdnav 4.2.0-2 [installed]
  The library for xine-dvdnav plugin.
extra/libdvdread 4.2.0-1 [installed]
   Provides a simple foundation for reading DVD video disks

命令的输出cd-info：

Disc mode is listed as: Error in getting information
++ WARN: error in ioctl CDROMREADTOCHDR: No medium found
cd-info: Can't get first track number. I give up

我应该检查一下系统日志。以下是journalctl我尝试使用以下命令播放光盘时发现的结果vlc：

答案1

这些是媒体 DVD 还是数据 DVD？您通常不会安装包含电影等的媒体 DVD。此外，如果这是包含电影和/或电视节目的媒体 DVD，您可能需要安装libdvd4软件，以便您的系统可以处理 DVD 上的加密内容。

请参阅我对这个问题的回答，标题为：无法在 Linux Ubuntu 笔记本电脑上播放 DVD。

光盘信息

您可以使用此命令cd-info --dvd来获取有关已安装 DVD 介质的更多信息。我的笔记本电脑中安装了《好奇的乔治》DVD。
