Can someone please help me. I am trying to convert a divx movie to SVCD with TMPGEnc but when i am getting no sound.

I have done this before with other movies and had no problems, i just add the video source and use that as audio too, and voila, it's done. However that is not working anymore.

I also tried having the audio as a seperate source, and when i tested it with a small bit of the movie it worked, but when i did the whole movie there was no sound!!

I should also say that when i convert other clips to (S)VCD i never have any trouble, it's just this damn divx movie. If it's any help the movie is a SBC DVD rip, done by JoeDivX.
