Hi there,
Unchecking exclusive mode makes the receiver run in PCM mode even when 5.1 is selected in the Netflix app, i.e. it's not playing in dd+
It also only seems to be specific to movies, any TV show that's available in 5.1 plays dd+ fine (when exclusive mode is checked). I only started having this problem when I installed the graphics driver from intel rather than the one that came via Windows update
Note, I'm running a D54250WYK with HDMI to a Yamaha AVR
