Thanks, but there are some serious problems.
After moving pardus_white.vlt to my ~/.local/share/vlc/skins2 (I have to create a directory skins2) and making the following modifications to Vlc (VideoLAN Media Player):
Vlc > Tools > Preferences > Interface > mark at "Skins" > browse to ~/.local/share/vlc/skins2/pardus_white.vlt > .... > Save.
After restarting Vlc it will not play my *.vob file and after this Vlc can not be closed.
And with the default settings or interface=Native I do not have these problems and Vlc will play my *.vob file.
