A couple of weeks ago I noted a problem playing the BBC Planet Earth BD. At Gonk's suggestion I tried the coax output to my 1070. When I set the BDP-83 to output bitstream over coax and the 1070 to use the coax, rather than analog, the sound was wonderful. BTW, I got all channels of analog, allbeit with Richard Attenborough in the next room with the door closed, only with Ext 7.1. If I switched to straight analog the center channel with Attenborough on it, was gone entirely. Using coax I also got a lot more bass.

I have contacted Oppo Tech Support to ask what's going on.
