Hello guys, i recently downloaded some movies off Limewire in (AVI) format, upon playing them, i realised that there is no sound at all, the picture is perfect but why am i not getting any sound??

I also noticed, that the movie files also say (Ac3)

I am using windows media player 8, what do i need to do, in order to play Ac3 movies in windows media player 8????

I keep hearing things about about Ac3 codecs, can someone plz give me futher details on Ac3 codecs/filter & how does one use them...

Appreciate any advice, thanx!
