I guess they're all about the same -- except that the "Directions for Samsung" indicate that the "TV needs to be on d/in" --- on my 2011, it is the DVD player that must be on "d.in" (which I assume means disc in) to get the surround sound. With the TV only on, the sound is out of only the TV speakers ---Duh!.
And, it's the forward speakers -- not the ones in the back over the beds.
Also, I'm ising only the remote for the DVD -- it controls the TV volume as well.
