Does VLC support DVDs from all regions?

Well this mostly depends on your DVD drive. Testing it is usually the quickest way to find out.
The problem is that a lot of newer drives are RPC2 drives these days. Some of these drives don't
allow raw access to the drive untill the drive firmware has done a regioncheck. VLC uses libdvdcss
and it needs raw access to the DVD drive to crack the encryption key. So with these drives it is
impossible to circumvent the region protection. (This goes for all software. You will need to flash
your drives firmware, but sometimes there is no alternate firmware available for your drive). On
other RPC2 drives that DO allow raw access, it might take VLC a long time to crack the key. So
just pop the disc in your drive and try it out, while you get a coffee. RPC1 drives should 'always'
work regardless of the regioncode.
 
Where does VLC store its config file?

Currently, a config file is created on a per user basis (there is no global configuration file). If you
modify the available options in VLC and save the new configuration, then a configuration file will
be created in your user directory. The precise location of this file depends on the Operating
System you are running:

Linux / Unix: $(HOME)/.vlc/vlcrc

Mac OS X: HOME/Library/Preferences/VLC

Windows 95/98/ME: C:\Windows\Application Data\vlc\vlcrc

Windows XP/2000: C:\Documents and Settings\username\Application Data\vlc\vlcrc

BeOS: config/settings/vlcrc
 
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 plugin, for instance:



Second, change your screen depth and/or definition. It quite often helps. Lastly, if running Unix,
have a look at your XFree86 video driver.

Video is choppy.

Your system might be too slow to decode all pictures. It might be that your CPU basically is not
fast enough. It can also be that the subsystem is misconfigured/misdriven, this happens for
example under Redhat Linux. Here are some elements to improve speed:

Turn on DMA on your DVD device, for instance:

Under Linux:



Under Windows, go to the System section of the control panel, and go to the Hardware
manager (it is sometimes in a separate tab, and sometimes, you have to go to the
Advanced tab. Then, righ-click on your DVD player, and check the DMA checkbox.

Upgrade to the latest driver for your video board

If you are running Linux, you can additionnaly upgrade to the latest XFree86 version. If
supported, check that the xvideo plug-in is effectively used with:



Stop other running applications

Try disabling framedropping. Framedropping allows VLC not to decode some pictures when
the CPU is overloaded, but can result in choppier playback under certain conditions.

Framedropping behaviour can be configured in the Video preferences of VLC.

 
Audio and video are out of sync

Try using another audio output plugin and, under Unix, kill esd or artsd if they are running. If the
problem is due to the input file, have a look at the "Audio desynchronisation compensation"
option.
 
VLC crashes.

Increase the verbosity level (either in the preferences or with a -vvvv command line option) and
look at the debug messages (in the terminal or in the Messages window).
 
How can I take screenshots?

To take a snapshot of the video displayed by VLC, you just need to press the pre-defined
snapshot hotkey:

Windows / Linux / Unix: Ctrl-Alt-s

Mac OS X: Command-Alt-s

To change it, go to Preferences -> Interface -> Hotkeys settings, check Advanced options, and
set Take video snapshot.

 
  Where are my screenshots?

If you haven't changed the snapshot directory in your preferences, your screenshots should go
to:

Windows: My Documents\My Pictures\

Linux / Unix: $(HOME)/.vlc/

Mac OS X: Desktop/

To change it, go to Preferences -> Video -> Video snapshot directory.
