The other is to use the 7.1 input for CD's as well as HD-DVD's, assuming the HD-A1 doesn't do any processing to it.
Thanks Gonk, I figured there might be some problems applying dsp to the 7.1 inputs. I am still confused about using the 7.1 inputs for CD's, I thought by applying BM on 7.1, the 990 needed to use it's DACS.
