I have the UE55KU6400 tv, Samsung support push me in the direction of my TV manual which states it supports DD+. I've asked numerous times if this includes support for DD+ over ARC which I suspect only supports DD - they state yes, I think no from my reading.
Customer service don't seem to know or understand. Has anyone any views experience?
I suspect ARC on this TV can only support DD. Much confusion, samsung need to sort this out... expensive hardware and no definitive answers
Does your AVR supports DD+ through HDMI input ? Depending your AVR capabilities, your TV may be transcoding DD+ to DD. Many new TV models must support DD+ over HDMI, since it is something mandated by Dolby Labs.
