I found this on yahoo! about the 2d to 3d converters:
So-so looking 2D-to-3D conversion
Both Samsung and Toshiba are promising on-board 2D-to-3D conversion on their sets, and as you might expect ... the effect only looks fair, at best. I saw a demo clip showing airborne views of a forest, a soccer match, a gushing creek, and so on, and the visuals looked ... well, they had what I'd call "pseudo depth," conveying the sense that the image was stretching behind the screen but not of a real 3D landscape. It's not terrible by any stretch, but don't expect an on-the-fly 2D-to-3D conversion of "The Empire Strikes Back" or Anderson Cooper to look anything like the real 3D thing.
