From DTS' web site:

"DTS-HD encoded content contains a DTS surround sound "core", plus an "extension" that delivers even higher quality. When you play a DTS-HD encoded disc through an older DTS-capable receiver, the DTS-HD extension is simply ignored and only the DTS core is decoded — but not at ordinary quality levels. Your older receiver will play back DTS-HD material with DTS surround audio at twice the data rate of other DVD video surround formats. Meaning? You get immediate compatibility and a boost in quality."

Since day one, all DTS decoders have had the capability of decoding DTS tracks up to 1.5Mbps, which just happens to be the bitrate of the "Core." Back in the old DVD days, nearly all DTS tracks were encoded at about 1/2 of what is now called the core bitrate, but there would be a DVD once in a great while that was encoded at 1.5Mbps. I remember folks trying to find these gems like they were looking for the Holy Grail.

Anyway, any DTS capable decoder can easily handle DTS-HD MA, or at least some parts of it.
