If you mean, how do you get your new Abby Road bluray to play,
- you can browse to the iso of the full disk (from video section) and just play it as a bluray
- you can extract the mt2s and convert them to mkv (and play as video)
- you can extract the mt2s and split it into separate mka files, and play them. (or just take the mkv, rename it as .mka, and kodi will “see” it as an audio file, complete with chapters.
- you can extract, and convert to flac, although you’d be down-coverting the DTSMA 8chan to something lower in that process.
If you have DVD-A, then you’d need to rip the mlp files out (google for tools to do that) and convert them to flac.
if you have SACD, then you’d also need to rip and convert to flac (google for tools to do that)
If you have DVD (or bluray) with dts or dolby tracks then you are probably best off just extracting the DTS/AC3 streams (into a .wav (or .dts) file for the DTS stream, or into an .ac3 file for dolby), and playing those streams as-is.
if you have DTS-CD, then just rip those like you’d rip a regular CD (into .wav files), which will then contain the DTS stream.
Noting that when it’s time to index your music, flac is the only option that really handles tagging well. Anything else you’ll likely be wanting to create .cue sheets for the metadata (which kodi does a pretty good job of picking up for things like date, genre, artist, album title)
