Kevin and Geaux,
Curious as to the modes you were successful with. I believe when I had mine working, I had the Mit's adapter at the first mode light (Meaning with only the power light on, one push of the mode button to bring on the mode light. I believe the 3d picture was best with the Samsung TV 3d set to mode 2. Does this sound correct?
Also, Geaux, when you had yours working for some time, were you able to go back and forth from regular programming and shut off and on and still maintain 3d connection?
I believe our problem may be with the DirecTv solely. If it works with prerecorded 3d programming and we can't get past the greyed out guide channels, D* may have the gate to restrictive. If they could open the channels in the guide and just warn of compatability problems, it may work with our current setups.
