Burned DVD, no sound?

Ok, I have Windows 7 on my HP Compaq 8510p. I'm trying to burn a DVD using the Windows DVD Maker program. I've wasted about 4 DVD disks so far trying to burn a movie, the picture is PERFECT, but no sound? The menu sound is working though? Now, I have already have the K-Lite Mega Codec Pack & the DivX Codec Pack along with the DivX Converter. I've already checked my sound settings in the Device Manager and properties. I've tried everything, so what exactly am I doing wrong? I've even tried using the Windows Media Centre program to burn my movie DVD, but still, no sound. I've tried it on our Blu-Ray player, DVD player and also tried playback on my laptop. What steps should I try next?
