There are two new DTS formats:

(1) DTS-HD Hi-Resolution Audio
(2) DTS-HD Master Audio

The first one is still lossy, the second one is lossless. As far as I can say, the first one "looks" to us like a normal DTS stream. So there's nothing special we have to do with it.

The 2nd one seems to have additional information in the stream which looks "unknown" to us. As far as I can say (with a hex editor) the two bytes after each valid DTS frame are hex "64 58" (which are the ascii chars "dX"). That might be the signature of DTS-HD Master Audio blocks. The size of these blocks seems to differ, depending on how difficult the audio signal is to compress.
