It turns out I needed to install the latest xf86-video-intel drivers
(2.20.3 in Gentoo), enable the Gentoo "sna" and "vaapi" USE flags, and
add the following to /etc/X11/xorg.conf:

Option "AccelMethod" "sna"
Option "TearFree" "true"

Those 1080p/60fps videos play perfectly now with 'mplayer video.ts' or vlc.
