I am following this guide:
https://www.videohelp.com/forum/userguides/154453.php

I seem to have probs at this part

5: Start Ifoedit and select "DVD Author", then select "Author New DVD"
6: Click on the dot to load the file .m2v into the video input open box
7: Click on the dot to load the file .mpa into the audio input open box
8 :Select the output stream destination to a directory called VIDEO_TS on your Hard drive

I have my two files, video and audio
when the program merges them to produce the vob files, that works
but my vob files have no sound
wtf?
i've tried this twice, same effect
my video is fine, but i get no sound
i already converted them to 48hz

help!
