1. Using VLC
It's exactly the same as for a normal DVD. You will need write access to
/dev/dvd, because of the key negociation process.
+If you compiled your VLC by hand, please bear in mind that you also need
+to install libdvdcss. It can be downloaded from the VideoLAN website. It
+used to be distributed in the same package as VLC, but now you must install
+them seperately.

1.3 How do I switch to full screen display ?
------------------------------------------
Press 'f' to toggle fullscreen mode. Note that not all video output
#@!£% *$@&§% !@# bloat ?
---------------------------------------------------------------------------
You can run :
- vlc -I dummy myfile.mpg
+ vlc --intf dummy myfile.mpg
Most commands are available from the command line, see vlc --help for
more information.
-----------------------------------------------------
If you don't know what is a raw device, don't even read this answer :-).
There is an experimental support for raw devices in libdvdcss. It needs
-that you set up a raw device pointing to your DVD device (under Linux,
+that you set up a raw device pointing to your DVD device (under Linux,
use the "raw" utility). Then pass the raw device as second argument, for
instance :
vlc dvd:/dev/dvd@/dev/raw0
-------------------------------------------------------
First you must set up a VLS or VLMS stream. Please refer to the
documentation of these programs. Then start VLC :
- vlc udpstream:
+ vlc udp:
You shouldn't need any option. If you're paranoid and want to control
everything, here is the exact syntax :
- vlc udpstream:[<server>[:<server port>]][@[<bind address>][:<bind port>]]
+ vlc udp:[<server>[:<server port>]][@[<bind address>][:<bind port>]]
+
+1.8 How do I uninstall / reinstall VLC ?
+--------------------------------------
+Why would you want to ? ;)
+
+If you're using a source distribution of VLC, for example a tarball or
+the CVS, then you have probably used "make install" to install the
+compiled VLC. To remove it just "make uninstall". If you want to
+install a newer version than the currently installed one, you should
+first uninstall the first one. If you deleted the original source tree,
+a "make uninstall" in the newer tree should still work.
+
+For binary packages, remove old packages first and install the new ones
+(normally this should be handled automagically by your sytem).
+
+1.9 Debian: what should I put in my sources.list for videolan ?
+-------------------------------------------------------------
+deb ftp://ftp.videolan.org/pub/videolan/ debian/
+deb-src ftp://ftp.videolan.org/pub/videolan/ debian/
2. Troubleshooting
* Do you have a link from /dev/dvd to your real DVD device ? For instance
ln -s hdc /dev/dvd
-2.3 Running vlc pussycat.mpg doesn't do anything...
-------------------------------------------------
-Probably your MPEG-1 file doesn't have any system layer. This is common
-for MPEG-1 streams without any audio track. Currently VLC doesn't
-automatically detect this format, so you have to manually select it :
-vlc --input es pussycat.mpg
+2.3 [REMOVED]
+-------------
2.4 The video runs but the picture is distorted...
-----------------------------------------------
There is probably a problem with the output layer. There are several
ways of troubleshooting it. First, try with another output plug-in, for
instance :
-vlc -V sdl
-vlc -V x11
-Second, try with an unoptimized YUV transform :
-vlc --yuv yuv
-Third, change your screen depth and/or definition. It quite often helps.
+vlc --vout sdl
+vlc --vout x11
+Second, change your screen depth and/or definition. It quite often helps.
Lastly, have a look at your XFree86 video driver (nVidia for instance
releases optimized drivers for its boards).
2.7 Audio and video are out of sync
-----------------------------------
-This is not normal. Try using another output plug-in (for instance -A dsp),
+This is not normal. Try using another output plug-in (for instance --aout dsp),
kill esd or artsd if they are running... This is a known problem and
is being investigated.
-2.8 On some DVDs the subtitles are unreadable
----------------------------------------------
-This is a known bug and is being investigated.
+2.8 [REMOVED]
+-------------
2.9 Sound volume is too low
----------------------------
-You can raise it with --volume command-line switch.
+You can raise it with --volume commandline switch or in the preferences
+window of your graphical interface.
+
+2.10 I have no image under DirectX
+----------------------------------
+Check that your video card drivers are in their latest version and that
+your DirectX is up-to-date.
+
+2.11 VLC crashes
+----------------
+Increase the verbosity level (either in the preferences or with a
+"-vvvv" command-line option) and look at the debug messages (on the
+terminal or in the Messages window).
+
+2.12 I can only play a DVD as root
+----------------------------------
+Check that as user you have write access to your DVD drive / device.
+
+2.13 I'm stuck with option xxx, how do I reset options ?
+------------------------------------------------------
+Under unices, remove your ~/.videolan/vlcrc; for Windows, remove vlcrc
+in the videolan subfolder of your "Application Data" directory.
