ac3 sound with xvid

[Simononline]

I've downloaded the Star Wars Episode 2 movie, got a xvid codec, and i can play it with media player, but it won't give a bit of sound.
I found out it has ac3 sound and my pc doesn't support ac3 sound, so there i am, watching the beautifull view, not knowing what the movie is about.
What do i do?

You need the AC3 decoder filter.
You can get it with the audio filters pack at doom9.
