I have read every post about getting dolby digital , dts , sound when converting a mkv to mp4 or any other file that a apple tv will play . I have the latest version of dvdfab8 and have tried to convert some mkv files multiple times and it will not allow itunes to see the correct audio . I have bought a video from itunes and it shows in the file that its dolby digital , but nothing that dvdfab converts will . please help or point me in the correct direction.
