AC-3 Audio

[falafael]

Recently i got the Aliens quadrilogy via the internet, the movies are in stereo, but with each movie is a seperate file titled AC-3, what i want to know is how do i get the AC-3 Dolby digital soundtrack merged with the movie so i can listen in 5.1!!
Tried alcohol 120, but i am lost as to how to get it working!!
Thanks for all replys!

What you need to do is find a app that will strip the sound off the film and try and replace with the ac 3 files I think the app you want is virtual dub but if I remember correctly its gonna be worth putting up with the stereo sound track or redownloading the film already with a dolby sound track as trying to sync the audio to the film is a royal PITA.
