Movies without Audio
 

My downloaded movies have no Audio. I've tried playing them in QuickTime and other media players, but still no audio. Any ideas would greatly be appreciated. I think it might have something to do with codec - but what codec?

Did you try VLC? http://www.videolan.org/vlc/ (choose nearest mirror site) Difficult to know what codec when we don't know what the file extension is. Did you have a look at the Sticky thread at the top of this section. I'm presuming you're using windows. If you were using mac you would have told us right!
