So I have a bunch of blu-ray mkv containing the h.264 codec. Some have DTS-HD, many have subtitles and/or forced subtitles. In order get these files compatible with the aTV, the DTS-MA needs to be converted to AC3, correct? Also, how do you take the PGS subs from the BR and get them in mp4 container, i.e. soft subs. What apps can do do one or both of these things and how forced subtitles that are not "burned in" work when changing the container from mkv to mp4? I hear a lot of people saying just convert your h.264 base mkv to mp4 using various software, but how easy and effective is that if you are not just dealing with torrents that have no subtitles and only AC3 audio?
