No BDLite Option is usually set to on. But this can be the reason because also with my 2D TV I get different 3D options based on this setting. It will take some time to check it with 3D Equipment again.
There is no need for an explicit frame packed option as that is automatically used when MVC is played. BD Menu is only for 50/60 hz camcorder iso, and so disables 24 hz support, and hence support for 3d MVC. It also means that only a single movie camcorder iso is expected, and so the first movie defines how the whole iso will be played, as with a camcorder that will be the only movie in the iso. You have to use the playlist feature and deduce which is the 3d one, and select it to get the player into MVC mode.
