No sound for video file?

Question

I have some files here I'm trying to play. The extensions are "HR.HDTV.AC3.5.1.XviD-NBS" I finally downloaded the Xvid codec 1.1.0 and that allowed the video to play, but now there's no sound. Can anyone tell me how I can get the sound to work? Do I need some other codec or what?

Answer 1

try this site- get the ac3 filter... sounds like you don't have one.

Answer 2

Try downloading this:
