I dont think you understand the issue.

You are right the sound bar is to take the place of the tv speakers. In that case why should there be the need to have two remotes.
The design is clearly flawed, its a poor design. You should have one remote and just turn off the tv speakers so that you are not controlling both (as you mention above, you only need the bar).
Why not just make them work together? why have two remotes to have one cohesive control? Its just poor planning. I would love to hear if I am missing something.....but I think i have it and Samsung has missed it.

its a real shame (and a scam the way its sold)!!

Thanks
