On a BD55 related note, I have a question.

Let's say I have a 7.1 system. I connect the BD55 to the 990 via the 7.1 analog inputs. I also setup the 990 do speaker/bass management and disable this in the BD55.

What happens when a play a disk that only has 5.1 Dolby Digital, whiuch I think just about all of them do. Will the player fill in the rear 2 channels (matrix???)or will they be silent?.

Thanks
