UbuntuHelp:RestrictedFormats/PlayingDVDs
来自Ubuntu中文
Most commercial DVDs are encrypted with CSS (the Content Scrambling System), which attempts to restrict the software that can play a DVD.
By installing the libdvdcss2 package you can play encrypted DVDs with:
- Kaffeine, the Kubuntu video player
- MPlayer
- xine
- Totem-xine
- VLC media player
- Ogle
Note : While Totem-gstreamer can play a DVD automatically when it is inserted into the DVD drive, it cannot navigate the DVD reliably (see Bug #41335). If you use vlc media player you can navigate through the menu, forward in the movie and select subtitles. Just select open disc, probe Disc(s) and click ok.

Setting DVD Region Codes
If your DVD player regularly locks up when you try to play back a DVD, your DVD player probably does not match the DVD's Region Code. Region Codes are a form of vendor lock-in. For example, you cannot play a DVD published in Japan (Region 2) on a DVD player in the United States (Region 1) without changing the Region Code of the DVD player (unless you own a region free DVD player). You can view or modify the Region Code of your DVD drive with the regionset tool.

> The author of regionset writes: "On delivery, most DVD drives have no region code set. The drive firmware allows you to change the region code, but on nearly all drives you are limited to five (5) changes. After the fifth change, the DVD drive will stay fixed on that code -- on some drives you can upgrade the drive firmware and have then additional five changes, on other drives you won't be able to change the region code any more."
- Most players (eg mplayer/vlc) with most DVD drives are able to ignore the value of the region setting. However, it must have been set to something; if it hasn't been initialized, even non-region-restricted DVDs won't play. Also, if it is necessary to crack the CSS key, it can sometimes take up to a few minutes to do so.

- To change the Region Code of your DVD player, insert a DVD from your region in the DVD player, and do the following:
- Install the regionset package from the Universe repositories.
- To launch regionset, issue the command
regionset
- See the Free Formats page for more information
Troubleshooting
- Jerky Playback
If DVD playback is noticeably choppy or burning a CD/DVD is slower than it should be, then you may need to enable DMA transfer for the DVD drive. See the DMA (Direct Memory Access) page for details.
