It works wonders for playing HDTV streams from mythtv. On a
somewhat
modern Intel CPU. Without it, HDTV is generally impossible. YMMV.
More modern CPUs might be better, dunno. A lot of HPC is done on
GPUs these days, so they're good for something.

I got lost trying to figure out what "it" is. Is it vaapi? If so, is
it enough simply to have vaapi-tools installed?

"it" = video hardware acceleration.

Yes, if you have Intel Graphics, vaapi-tools should be enough. Then
run vainfo from a konsole, and it'll tell you.

What is it actually telling me?:

# vainfo

libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib64/dri/i965_drv_video.so

This means you have hardware accelerated video. vainfo talks to the
driver and the driver talks to the hardware. If you're using MythTV,
you should be able to enable it somewhere in settings - renderer = auto
or something like that.
