The $500 Panasonic DMP-BD30 can send DTS-HD MA via BITSTREAM, but it cannot internally decode it. So if you have a DTS-MA receiver, that would work.
Is your new Yamaha receiver DTS-MA capable?
I've also heard that Sony is working on a firmware for DTS-MA bitstream for PS3, but I'll believe it when I see it.
The $800 Samsung Combo BD-UP5000 is suppose to be able to internally decode DTS-MA, but until I actually see it with my own eyes, there is still doubt.
DTS is such a pain in the A$$!
