Here's a screen shot confirming the blu ray Storks 3d has 7.1 dts master sound.When hitting the audio button in Fab settings by right clicking mouse and select audio Fab reports 5.1 sound.Does this mean Fab media player is not playing 7.1 sound or reporting it not correctly?
All settings are set for 7.1 digital sound in Fab settings all forms of digital sound are checked marked as my receiver plays all.
