I've noticed on all of my NEXT a/c over the past few weeks, I've been shown the new safety video (including NEXT 738/739). On non-NEXT a/c (specifically DTV 738/739), I've been shown Safety is Global consistently.

Is it a software update that makes it so only one video can be loaded on each plane at a time? Why can't they upload the new video on all a/c at once? Not complaining since I also prefer the old video, but it creates a consistency issue imo.
