Sound is missing

Once again sorry about my poor english. Well i´m using the main concept mpeg encode and the fddshow to add subtitles into avi movies, in order to save espace and put 3 or 4 movies in the same dvd. The problem is that when i encode the movie from avi to mpeg1, whith mpeg layer 1 or 2, the movies lost the sound. The subtitles are there, but the sound is missing :confused: .
Some gentil soul can please help me ?
Thanks
