I finally narrowed it down to CloneDVD as the root of my no sound problem. The video_ts files have sound after i compress in dvdshrink, but the disks turn out without audio on the main movie (menus, special features have sound). when i first burned dvds two weeks ago, they were burning fine with sound. this is a recent thing and no settings have been changed. anyone else having this problem or know how to stop this from happening?
