I also think the playing of videos in place of the human aspect of having a real person as a speaker depersonalizes the meetings. It may sound cool at first to watch professional videos, but I think eventually it will lead to a distancing mentally from the meetings. Probably not by all, but by some. Little to no effort by meeting speakers makes it easier on the BOE to be sure, and good for them...it was a nutty schedule to try to keep up effectively as a "shepherd."
I would think maybe it would make it easier to miss meetings if you thought, "oh I'm really tired...well tonight is the video night, I can catch it another time or go to jw.org."
Just a thought I've been tossing around for a while.
