Any update on half-SBS in XBMC?

looking forward to xmbc implementing the boxee 3d features. while i don't mind the menus, mostly the subtitles (avatar, anyone?) are a problem currently while playing 3d content.

Sure I can explain further.
You see the GT430 IS a 3D capable card. What that means is when you are using 3D capable software (aka PowerDVD, not XBMC) it can go into a full 1080p 3D mode allowing you to play 3D Blu Rays like a 3D Blu Ray player can.
On the other hand, half-sbs is a hack. Its not even a real standard. What it is is half-resolution 3D that is encoded that way so it can playback on current 2D hardware. That is why you have to force your TV into 3D mode with half-sbs, while if you play a 3D Blu Ray with PowerDVD it does that for you.
What I imagine is happening is that the Nvidia driver performs differently in its true 3D mode. Maybe Nvidia turns down the post-processing, or maybe even its enhanced for 3D.
With a half-sbs file the Nvidia driver thinks its playing in 2D mode, hence it turns on its 2D post-processing.
Basically half-sbs is not real 3D. It is a hack because 3D is nasty now (incompatibles with HDMI 1.3 receivers, no unified 3D framework with AMD and NVidia, etc.) yet people want 3D. Technically you don't need a GT430 to play half-SBS files- any ION system (or GT210) has enough power.
What you are paying for with a GT430 is a true 3D mode that is only available with PowerDVD (and other software like it).

It seems good, but then you compare it to alternatives (for me my Samsung TV can play the files directly) you quickly learn how off it is. With VDPAU the crosstalk is about as bad as it gets.

I only see mention of getting this to work with Nvidia...is there no way for ATi cards to handle this?

What I am really missing is playing back half-sbs movies in 2D mode. I don´t have a 3DTV yet (just bought a 2D plasma 1,5 years ago), so I am currently forced playing them back on Windows with the 3dtv player/PowerDVD in anaglyph mode (cheap solution and better than nothing; IMHO better than it´s reputation). Nevertheless, I am sure to buy a 3D capable PC monitor first before upgrading my living room, but this will also take some time...
However, I started reencoding and collecting sbs 3D movies, and playing them back in XBMC in 2D is not possible as I haven´t seen any scaling/cropping options that would allow me to cut off the right half of the video and scaling the left half to full screen. I have checked the zooming/aspect ratio settings, but I haven´t found a way to get it working.
I am currently using XBMC within yaVDR (Linux) - playing back those half-sbs movies always means a reboot of this living room PC to the second partition that contains Windows with the 3dtv player/PowerDVD... I don´t expect you to implement anaglyph playback (see some example avisynth conversion code at http://www.pc-magazin.de/ratgeber/von-youtube-co-zum-wohnzimmer-3d-1022195,6508.html (sorry, German), but at least this scaling feature would be nice as a first step
BTW: Concerning the discussion on how to detect a MKV 3D encoding: New flags have been introduced that allow you to tell if and how a movie is 3D encoded. See http://www.matroska.org/technical/specs/index.html#StereoMode for more details on this.

I currently don't have an AMD card as I sold my tester Radeon HD 5450 recently. I hope to test broadcom when I get my hands on the old AppleTV1 this summer that my sister has at college now.
