"Fake Interlaced" is needed where you want N fps progressive (because you have a progressive source at N fps), but the BluRay standard only allows for N fps interlaced (i.e. 2xN fields/second) - not N fps progressive. x264 will then create an "interlaced" stream (to make BluRay happy), but simply code all blocks as "progressive". That's possible because even in "interlaced mode" H.264 still allows to select between interlaced/progressive for each block (MBAFF). And about the "--bluray-compat" option: It is required but not sufficient to get 100% BluRay compatibility. I guess that's because there are some things that are always needed for BluRay compat and other things that need to be adjusted.
