Netflix decides which devices get what level of service, and even what interface.
Oppo just doesn't have the volume to make Netflix and their decoder manufacturer take notice. I would think that the sort of positive reviews Oppo gets would influence Netflix. But I guess volume is king.
It is unlikely that we will be able to add Netflix 1080p and 5.1 audio support through a future firmware release due to limited resources from Netflix and our decoder manufacturer at this time.
