  # download the desired resolution
  youtube-dl -f 137+141 XXXX 
  # Note the two numbers 137, 141 is case dependent. They could be 137 & 140.
  youtube-dl -f 22 XXX
  # if the format 22 is mp4. If I do not specify the format, the mkv file will be downloaded
  # But playing mkv file tends to be stuttering with VLC.
