1. Using VLC
Just launch vlc and use the "open disc" command from the graphical
interface. In case of trouble, you may want to use the command line
interface :
-vlc dvd:/dev/dvd
+ vlc dvd:/dev/dvd
1.2 How do I read an encrypted DVD ?
----------------------------------
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.
+1.6 VLC eats my buffer cache, how to I use raw device ?
+-----------------------------------------------------
+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,
+use the "raw" utility). Then pass the raw device as second argument, for
+instance :
+ vlc dvd:/dev/dvd@/dev/raw0
+
+1.7 How do I use VLC as a client for VLS/VLMS streaming ?
+-------------------------------------------------------
+First you must set up a VLS or VLMS stream. Please refer to the
+documentation of these programs. Then start VLC :
+ vlc udp:
+You shouldn't need any option. If you're paranoid and want to control
+everything, here is the exact syntax :
+ vlc udp:[<server>[:<server port>]][@[<bind address>][:<bind port>]]
+
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 When I try to compile VLC, it breaks on unknown instructions in
-idctaltivec.c
----------------------------------------------------------------------------
-Unset your CFLAGS environment variable. For instance type
-export CFLAGS= ; ./configure
-Don't try to be cleverer than us :-).

-2.10 Sound volume is too low
+2.9 Sound volume is too low
----------------------------
-This is a known problem.
+You can raise it with --volume commandline switch.
3. Ports and features
Currently it doesn't. We'd be glad to support them, but we lack technical
information on them.
+3.2 Win32 port
+
+3.2.2 When moving the focus to another window, VLC network input stops
+working properly !
+---------------------------------------------------------------------------

+system.
