Russo, I checked your website (very nice, by the way) for your zip code, there are 8 Samsung dealers within 25 miles of your zip code. At least one of them should be able to help you sort out your system issues and changes. And perhaps give you some training as well, you seem to have an inclination to want to understand your system (kudos for that). Invest in a little training, it will reward you in the long term.
