I'm just going by what I read here, mostly in the "insider discussion" sub-forum. That and people having polls about which is better (similar to the DTS versus Dolby lossless comparisons here) that people get wrapped up in to the point of saying things like 'too bad it wasn't AVC' for a particular movie's release. At least with this film there's a true comparison to be made but not so with just about anything else. This film could be a really good point to be made about which codec is truly "better".
