For the actual animations stuff (the screen refreshes, but not 
necessarily the alphapulse), IIRC, 70Hz was chosen because of the 60Hz 
beat of the seconds display in the clock--we needed some value >60Hz to 
ensure we didn't skip any seconds.  Stuart M. could probably give a lot 
more detail when he returns.

Also, remember that this pulsing is in the UI, not the OSD, so video 
frame rates/refresh may not be that important.  I'd expect we have a lot 
of people running at 1080p60 or whatever because that's what their TV 
supports, and maybe they drop to video-matched modes for video playback.

That said, optimizing it would be good--but I just hope we don't throw 
out the baby with the bath water.  :)
