It does appear I can play back a DTS HD MA track fine. Mind you it must be just the core portion as I am using SPDIF on a receiver that doesn't support DTS HD MA. I would really love to know if someone has a proper receiver and has the full DTS HD MA support. I just bought a Onkyo HT-RC180 but it won't be here for a while.
Used Band of brothers disk 1, track 1 on that is DTS HD MA.
ALL my problems in the first post were network related, as in the box won't play bluray rips over the network. Thats a rather HUGE down side, I may just end up returning this thing if I can't get some fixes for that.
