DTS, PCM, and AC3(which is Dolby digital). I obviously selected ac3 and now I get Dolby 5.1 from my Xbox 360 which is connected to the TV only through HDMI.
Thanks for the tip slosrtnick.
I finally took the effort to figure out how to enable the service menu for the TV. It turns out I did not need to spend so much time. I ended up just adding the TV to my Harmony One remote as a new device and "EZAdjust" shows up as a button option. Pressing that and entering the 0413 password previously posted got me into the service menu. I flipped one of the options (I think it was Menu 6) to AC3 and now DD passthrough works on all HDMI inputs.
I also turned on the Local Dimming option on Menu 2 and 4. I now have a Local Dimming setting in Picture Options that goes Low-Med-High. I know some folks have played with this in the past with mixed results. Did anyone try the different levels and was there any noticible difference? I will check it out tonight and post my results but at first glance I did not notice much difference between Off and the 3 levels but it is daytime and things look a bit different at night in a dark room.
