Well if your Yamaha receiver accepts the toslink optical cable and decodes normal DTS from DVDs, Blu-ray players can output that through bit streaming, so check output specs on Players, etc.
Since Blu-ray Disc can do up to lossless DTS-HD Master Audio 7.1 sound, (plus LPCM and Dolby TrueHD formats), in this forum, when they talk about that original DTS format they usually refer to normal DTS as "DTS core" or "DTS 1.5 Mb/s", etc.
There's also lots of more info at our
Audio Forum like the first sticky at the top etc
