[ubuntu-za] Vlc Player not Showing video

[Bruno Marques]

hello there

i dont know why, but when i tried to play a movie today on my ubutnu 
9.10 machine, the video player that i use, vlc isnt showing any sound..

the movie is playing, but no sound appears, instead the window where the 
video should appear is completely transparent, i've tried other formats 
of video but its the same thing... is there a setting that might have 
ticked off this?

many thanks in advance

regards
