My current question is, would this new mixed output be presented as LPCM or would the player manufacturer have the choice of re-encoding the mixed primary and secondary stream to DTS HD or Dolby TrueHD?

The mixed output would have be output from the player as

- LPCM via HDMI
- LPCM via analog outputs
- LPCM encoded to DD or DTS via SPDIF output. This DD or DTS bitstream could also be via HDMI although that is not popular.

There is no encoding to DTS HD or Dolby TrueHD in the players as it is too CPU intensive.
