The Pi currently supports half-SBS and half-TAB (i.e. resolutions up to 1920x1080).
You need to have "Adjust display refresh rate to match video" and your display need to report 3D support through its edid (check with tvservice -m CEA).
Technically the Pi's video hardware is only designed for 1080p30, but that is for the theoretical worst case streams, and for typical streams it can run a lot faster.
It also overclocks quite well, so decoding 3840x1080@24 is not completely impossible.
I believe that vdec3 can handle MVC, but last time I checked it wasn't being used by any customers, and so fixing problems wasn't a priority, and it wasn't quite plumbed in fully.
But 1080p half-SBS/half-TAB does work now.

I have no idea. What am I doing wrong? My TV switches automatically into 3D mode but movie is displayed incorrectly. After I switch off 3D mode on my tv, I can see entire movie is displayed at top part. Displaying movie should be untouched - only gui should be splitted.
I belive you when you're saying it works. But, as you can see for me it doesn't work. Do you have any idea what am I doing wrong?? I don't know if this makes any different, but I need to set 1920x540 (because I'm using 3D mkvs written on bluray discs, so I can't change their names to htab).
I'm not sure what do you mean by "Adjust display refresh rate to match video", where is this option? Maybe this is the reason?

for half 3D, the only thing that's important on the player's side is the refresh rate.
That is because the player doesn't even need to know if it's outputting 3D or not. As far as the player is concerned, it is a regular 1080p or 720p stream.
The display on the other hand, has to be able to convert the sbs or tab frame into a 3D sequential mode to display it properly. Now the only tricky part is, not all 3D displays will accept all 3D formats at all resolution and frame rates.
For instance, most 3D projectors will process over-under (or tab) at 1080p24 and 720p60, and sbs at 1080i60 or 720p60. If you try to feed 1080p60, the display simply won't accept it and the 3D option will be greyed out. If you try to output sbs at 1080p24, it will treat it as tab and it won't be displayed properly. If you display tab or sbs at 720p60, it will force you to select tab or sbs, you get the idea. (Now, on your tv, things may be different)
"Adjust display refresh rate to match video" is an option in xbmc settings and it allows you to output at 24p (as long as the video is encoded in 24p)
So if you're trying to display 3d-TAB, just check that option so you output 1080p24, and on your display, you *might* also have to select top-and-bottom or over-under in 3D settings

1) auto switch is not working yet - I was wrong about that, sorry. I'm working on a PR that implements this (modes: ask if 3D detected, auto-switch 3D, convert 2D)
2) what do you mean? On startup?
3) no, not yet, as the auto switch is not yet there. As said, I'm working on it.

Hello,
Sorry for offtopic, but where can I download it from? I've searched in this thread but I can't find any link.
