With a DTS encoded disc, surely can we not just get the disc player to output PCM to a Theatre?
I might be missing something, but I thought it was just a matter of choosing which device in your chain does the decode/ unpack of the source signal. So whether the player does, and sends out PCM, or alternatively it sends bitstream (i.e no decoded) onwards should not really make any / much difference.
Obviously with a Theatre not doing DTS-X, one would need to get the media / disc player to do the job and just send out PCM.
Or am I missing something?
