The two different aspect ratios must be a typo. Both the 3D and 2D Blu-ray versions are 1.78, as is the previous Blu-ray Extended Edition. On the Extended Edition, the bitrate for the opening few minutes often bounces around in the high 30s, even going as high as 41.4 and rarely dipping below 24. That same area on the 3D and 2D versions on the same disc usually peaks in the low 20s and even dips as low as 10 at times.
While I have to say, the 3D presentation is quite stunning, it does make me wonder what could have been if they had used the entire alloted space for the 3D presentation only instead of trying to put two three-hour movies on the same side of a BD50. Perhaps there is something about the process I don't know, and the 2D version is simply one eye of the 3D presentation, so not extra space is used. If true, though, why the much lower bitrate for a movie that is 16 minutes shorter than the Extended Version? Does anyone know more about the actual process?
Ronald, regarding "I, Robot," I haven't had a chance to look at more than the first ten minutes or so, but it looks like precisely what it is: a 3D Conversion. It's not bad by any means, but it's not on the level of "Titanic." At times it has that cardboard cut out quality, and other times it just doesn't look 3D at all. There are lots of scenes with a lot of fast motion, and since 3D has always had a hard time with that, those scenes hurt my eyes.
