Yup.  I just saw essentially the same thing by playing it with mplayer.

Actually, they could send 720p60, but they're sending 720p59.940.  Those
are two different formats (of the 17 ATSC formats).

Why not send it with the original fps?  The networks are just too stuck
in the habit of doing everything at 59.940fps.  Perhaps there are issues
with switching rates between programs?  I would like to think that they
could easily switch between any of the 17 formats, even in so far as
having consecutive commercials in different formats.

As to SW:AotC, I'm guessing that it was encoded by the network, not the
individual stations, so if any one station couldn't handle a different
fps, they couldn't use it.  Of course, when two consecutive frames are
identical, it doesn't take much additional bandwidth.
