I'm having problem getting DTS-HD MA on my receiver. PowerDVD 10 says that it's outputting DTS-HD Master Audio 5.1 but my receiver says it's only DTS.
I have actually never seen it display the DTS-HD MA logo with audio from my HTPC, only from my PS3. Windows 7 reports that it supports all the HD sound formats.
ATI HD6670 connected with HDMI to my receiver
Marantz SR6004 receiver
Sony HW-10 projector
Windows 7 Home Premium 64bit
Tried mostly with Avatar and The Black Knight BluRays-
