blu-ray audio standards

[kinglerch]

Can all blu-ray players handle DTS? Dolby Digital was the standard for DVD, so DVDs with a DTS track had to have a DD track too. Did DTS become the standard for blu-ray, so blu-ray discs do not have to include (an essentially duplicated) DD track too? Or for all blu-ray players to be able to decode multi-channel audio, both types must be included?

I recall that Blu-ray requires at minimum a PCM or AC3 DD track in addition to DTS similar to DVD. But for personal use you can author with just DTS if you want. If you think your BD disc will be ripped, best to include AC3 DD as well.

I was under the impression that blu ray players that are not capable of playing DTS-HD MA audio would switch to the lossy "core" DTS audio.

Which authoring programs can handle DTS-HD?

You'd think so, considering how many Blu-Rays only have one primary English audio track, often DTS-MA. (e.g. LOTR extended discs for example) Apart from commentaries, etc.
