format code  extension  resolution note
low          mp4        320x180    
medium       mp4        512x288    
high         mp4        854x480    (best)

But when I check JSON data at website, I can see better video is there. Like:

Here is the video I tried to get.

youtube-dl http://www.ted.com/talks/ismael_nazario_what_i_learned_as_a_kid_in_jail --max-quality

It gets marked with (best).

My question is why youtube-dl does not gets better one?
