I can personally confirm that the UN65ES8000 (probably other size ES8000's) work.
However, the picture seems very dark. Also, I recall reading that it won't work with 3D, which is kind of weird since it is a 3D TV. Why would they not enable it.
Also, I am not sure how the quality of the picture really is because it is connected via my router to the HR34. From what I read, the ethernet port on the TV is NOT a gigabit port. Also, I am not sure how well a single cat5/6 cable can handle the data needed for 1080p. I don't know too much about this, but most HDMI over CAT5 adapters use 2 cat5/6 cables.
Has anyone here really tried it?
Also interesting, I haven't actually activated it. It gives me the screen that asks me for the code on my HR34 to pair them together. However, since I haven't activated it with DTV, it won't let me continue. However, it does seem to allow me to swap my C31 connection with the Samsung. It said something like "you are only authorized for 1 client. Would you like to change the client to a new one?". Seems like it will let me swap on my own. I just was afraid I would mess something up, so i didn't proceed.
