These are hardly comparable to FMA Brotherhood. FMA is sub HD (so somewhere below 720p), and these are real 1080.
There's a certain amount of aliasing in most scenes, but not terrible. The animation, backgrounds, etc, are all really good, better than I hoped for.
Now the ugly part, is the encode. It uses a AVC encode at 30mbit+, which sounds ideal on paper, but either the master was handled badly (no proper dithering), or they just put zero effort into the encode, thinking high bitrate is enough (I suspect both).
The result is massive omnipresent banding, and even worse: blocky banding (which does suggest a poorer encode).
Still, considering the amount of detail and resolution, buying it on bluray is clearly the way to go if you want to watch it.
