Aimee,
As I read these directions more closely, I realize that they are not applicable to the system in my 2010 2551. As I already replied to rannan5050 in the other post, the DVD and Surround Sound directions are different. In addition, the "using one remote" directions are also different, for mine the TV remonte is the samll one and the DVD remote is the large one, and the buttons described don't exist on my remotes.
I do have a Samsung TV and DVD, but maybe these directions are for older or newer models?
