powerdvd 11 is apparently limited to dts-hd 5.1 but when i play my discs with dts-hd ma 7.1, the input audio is perfectly detected as dts-hd ma 7.1. also, audio comparison against 12/13/14 is perfectly downmixed to stereo [as i'm using stereo speakers 7.1 has to be correctly downmixed]. so where is the limitation? is it hdmi/spdif/analog output? because the input seems fine as far as i can tell
thanks
