I understand that these features need to be implemented by Apple. However, if these features are not requested by a considerable amount of users and developers, it is unlikely that they will ever appear on Apple TV.
I would therefore suggest that Firecore encourages users to contact Apple and request these features. This could be done by opening two new “official” threads: “Help getting bitstream HD audio on Apple TV” and “Help getting 3D (Frame packaging) on Apple TV”.
Is this feasible?
