Hello all: I have aquired my first DVD player and would like some input regarding the digital outputs it has. Until I can upgrade, I will be connecting my Sony DVP-S360 to a ten year old Sony STR-D2020 receiver. This old unit has both optical and coaxial digital inputs. Which is better- if there is a difference? Also, I would like your input regarding my surround speakers. Currently I have a pair of Realistic Minimus 7's mounted about 8 feet behind my sitting location,and 7 feet off the floor, and a few feet wider than my front speakers,(An old pair of JBL Decade 10's, but that's another story)angled slightly inward. This arrangement suits me fine for my limited system, but I am anticipating an upgrade for AC-3. My concern is their mounting position. Is this high and wide position desirable for the newer systems, or should I be anticipating some drywall work to move the surround location? Thank you for your guidance.
