Fix to make vlc run under Bactrack - Making VLC run under the root:-
Steps:
1. Open the terminal.
2. Write this command. 

       hexedit /usr/bin/vlc

3. Hit enter.
4. Press tab and you will see that blinker has been shifted to the 2nd group. 
5. Now Find this

       geteuid._libc_start_man

 Find this by scrolling the mouse wheel or else pushing the down button.
6. Now replace with this by

 getppid.libc_start_man

(i-e you just have to change the word take the pointer there and then just write; and you will see that alphabets different from the already there will start getting replaced by newly typed)

7. After above process press ctrl+s 
Type y

 You are done now
In the same terminal type vlc and hit enter. Woa! It runs now. Tune the speakers and let it go.
