Did you go into the NVidia setup menu and enable 3D. Go through the 3D setup wizard and set your res to 1080p 24hz.
I can't help with TMT 5.x but it can be a pain to get 3D ISO's to play correctly on any media player. I have Power DVD and it works fine.
Your glasses are OK and projector is set right.
The 3D thingy is for RF glasses and doesn't need to be connected.
If 3D is working the screen should have a reddish hew to it and picture should be fuzzy without glasses on.
The 3D settings are grayed out because NVidia 3D is most likely not enabled
