So I realized this morning that all my movies no longer have sound but they do have picture. All the chapters are now gone. I did a massive Metax tag a few weeks ago where I changed the release date and I assume that caused the chapters to go away and the sound. Also some of my movies after metax tags are missing audio and video. Does anyone have a solution for this to make it not do this anymore? Furthermore how can I repair the corrupted files? I have about 200+ movies that this has a problem in and I wish to not have to redo all my movies in handbrake. Please help. FYI, using Handbrake and Metax on Mac. Thanks.
