I use Cucusoft AVI to MPEG converter pro 4.33 to convert my AVI movies to DVD complient MPEGs. Then I use TMPGenc DVD authoring or Roxio EZ DVD Builder to make my DVD. When I preview the DVD within the authoring program the movie has sound. When I burn the movie or make an image or video_ts files, there is no sound. Even the sounds in the authoring program itself, such as the menu sounds and such dont show up. What can I do to solve this problem?
