Careful with the channel calibration. If you are using the analog outputs, the Oppo time delay algorithm can only support surround speakers that are installed closer or equal to the listener than the fronts.

Since we're on the topic, I was really not thrilled with Oppo's response on this issue (see below):

Me: Hello, a few weeks ago I cancelled my > order for the 971H. I cancelled the order because your time delay algorithm can only support surround speakers that are installed closer or equal to the listener than the fronts. When do you plan on
changing the algorithm? I feel like I am being penalized for
installing my surrounds further from me than the fronts.

Oppo: The algorithm for the delay is based on the Dolby Digital specifications. For this reason, we have no plans on changing the delay functionality of our players. For most applications you will not be using the channel delay functions on the DVD player, as you will be using these functions on your receiver.

Me: I have used three different integrated receivers and they all support surround speakers that are further away from the listener than the fronts. So I very much doubt that your implementation is a limitation of the DD standard but rather an over-sight on your part. I don't have HDMI on my current receiver. I therefore have to use the analog inputs for 5.1 surround to enjoy SACDs. My receiver, as with the majority of receivers on the market now, cannot apply time delays to analog inputs. I am very disappointed that you would not even consider this request for future corrective action.

Oppo: Our engineers worked closely with Dolby Labs on the design of the channel delay circuitry. The way it is integrated into the system is based on their recommendations. We have no plans on altering this implementation as our engineers are not familiar with the algorithms used by receiver manufacturers to add delays in the positive direction.
Our engineer team is quite small, and we do not have the resources to train an engineer specifically for this function.

Needless to say, Oppo is not on my list of A/V vendors any longer.
