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 those 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.
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:
Often this is caused by video hardware overlay problems:
If it is only one video then use the Settings menu, option Extended GUI and try to increase the Gamma value in the Video tab.
Check your video card settings and turn off hardware video overlay. If the videos now play with proper lighting, then deinstalling and reinstalling the video drivers might help.
If you are on Linux/Unix, did you install the libdvdcss package?
Do you have write access to your DVD device? For instance, from the console: #chmod666/dev/dvd where /dev/dvd is the device corresponding to your DVD drive.
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: #hdparm-d1/dev/dvd
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.
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.
Try using another audio output plugin and, under Unix, kill esd, artsd or pulseaudio if they are running. If the problem is due to the input file, have a look at the Audio desynchronisation compensation option.
Increase the verbosity level (either in the preferences or with a -vv command line option) and look at the debug messages (in the terminal or in the Messages window).
If you are convinced that it is a bug in VLC, have a look at the bug reporting page.
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. You can also take a snaphot via the menu Video → Snapshot. To change the snapshot format or directory, go to Preferences → Video.
Are you sure VLC supports the file? Try checking the features page. If it supported and you compiled VLC yourself, check if you have downloaded and installed all the codecs correctly. If it is not supported, then you are out of luck for now.
If VLC has autodetected your subtitles file, or if you opened it manually, but VLC only displays some subtitles from time to time, you will need to change the subtitles file encoding.
To do this, go to Tools → Preferences → Subtitles/OSD, and select the right encoding format for your PC in the dropdown menu and click Save.
