I have a stupid question. When I listen (watch) DVDs they are much softer than CDs. Comfortable listening volume is about -20 db for CD but at least 0db, maybe +5 db for DVDs. It doesn't seem to matter whether I decode as dolby digital or another souround format. Both plaers are form Sony, both are connected to the 950 via digital interconects (from Outlaw). Is there an adjustment somewhere to boost output level for DVD?
