Help with divx plus sound!

Okay so here's my problem I just recently installed divx plus so that I could watch a movie I've downloaded via torrent, but not pirated, but when I went to play the movie I had no sound what so ever, but the weird thing is is that I have the sound up almost all the way on my laptop and the sound is turned all the way up on my divx plus, so I don't get why I have no freakin sound, any help with this? it would be greatly appreciated.^^


edit: Okay guy's need help with something other then the sound, I need a more updated ver. of divx the one I downloaded was 4 plus but I need a updated ver. for windows, I have windows vista home premium, any help with THIS would be appreciated. thanks!^^

edit 2: Nevermind guy's I found a different media player called winamp that plays movies and streams music without the the need of a codec program so some one can lock this.^^

 

SOrry for the late reply, seems you've figured it out yourself.
I would also recommend VLC

It has its own internal codecs and you'll never need to install anything to play media files with it.
