What SUCKS is that the player duplicates the surround channels of a 5.1 soundtrack into the rear surround outputs, thus preventing the AVR/processor from having the option to apply alternative processing such as PLIIx, Logic7, etc, or the option to do nothing--hearing the 5.1 in it's original perspective as created. I realize this is a DTS requirement--not Oppo's invention, but Pioneer, for one, is dropping this silly idea due to all the consternation it causes. I really hope Oppo does the same--or at least gives us an on/off switch so we can opt out of this nonsense.
ETA: I'm assuming this duplication trick happens on both the analog and HDMI PCM outputs. If it only happens on the analog outputs, it is less of a problem. I'll get my player in a few days so I'll be able to confirm.
