Oliver Stones Untold History Of The United States S01E06 720p HDTV x264-EVOLVE

where is the standard def x264 version of this episode and episode 1? the other 8 are listed, but
not 1 and 6? it's a waste of bandwidth to download the 720p versions when i don't want or need them,
but i would like to see the entire series. especially when you live out in the country and have a
slow internet connection.
