Please use builds from this thread if you are reporting issues in this thread, otherwise it just gets confusing.
These builds are actually closer to Isengard than the current OE beta (which is actually rather old).

Anyway, with these builds there is a GUI option in video/acceleration settings to disable frame packing modes.

So I'm on #0615 now, OpenELEC (unofficial) Version: devel-20150615210217-#0615-gd9c8225, OpenELEC git: d9c8225c2037a1575de830ef819cb6f239177620

The option in video -> acceleration was there before, I already tried it, and the behavior is the same. It doesn't initiate FP modes on the projector, but the only thing that goes SBS or TAB is the GUI itself. The video will always be displayed monoscopic, no matter what 3D type I choose at the beginning, because this only influences the GUI, but never the movie itself. I also don't understand the logic behind it - the movies are already encoded as SBS or TAB, so if Kodi wouldn't touch the movie at all, it would play fine.

It's a shame I basically lost all working 3D options, and have to consider downgrading to Helix in order to get them back - or remove the 3D flag from the movie names so Kodi doesn't touch the movies when they are played back.
