The manual says that the best way to configure an output device is to have it send PCM. I will likely purchase the Oppo BR player and its instructions indicate that it should be configured to send out bitstream if you want surround processor to do all the processing. If you set the Oppo for LPCM over HDMI it will do the decoding/processing. Is this a problem?
