in my HTPC I have powerdvd 12 installed, a Geforce 430 and an AMD Phenom II X4 940, Win 7 and a Panasonic HDMI 1.4 Plasma and a Pioneer HDM 1.4 AV receiver that can handle anyting.
Powerdvdv's 13 advisor give all checks green both on 3D and BD. Though is says nothing on HD audio
Still: no 3d and no for HD Audio both on BD iso's and mkv's. Any ideas?
Further relevant info:
TMT5 does 3d and HD audio sometimes (it refuses some MKV's or iso's) and VLC player does everything right except HD audio of course, but that didn't come with it
