A:AnswerI was concerned about the same thing. I asked when I purchased the set and the salesman tried to convince me to buy a sound bar. I am 80 and midly hard of hearing. I am fine with the TV speakers. I do not need a sound bar.
A:AnswerIt uses the standard Samsung remote code... What DIRECTV remote are you using? The newer remotes (rounded, smaller)... will auto setup through the STB.
Else you can try going to: http://www.directv.com/DTVAPP/content/remote_codes2 to find the codes
A:Answeryes it is good. You will probably want to turn auto motion to the "clear" setting though. I noticed in 3D mode even with automotion off you still get the soap opera effect. With the "clear" setting I don't get it. But yeah the 3d is great.
