Will jog/shuttle dials ever make a comeback on disk player remotes? I used to enjoy stepping back and forth a frame at a time examining animated films on laserdisc. Are there remotes today that work well for that? Back when DVD arrived, I read that it wasn't possible with DVD because each frame really just contained the modifications needed to change the prior frame; so each frame wasn't a complete frame. I assume the same is true of blu-ray and 4K. Okay, but can't a high end player have some on-board memory to store a couple minutes' worth of complete frames? There's a tiny visual gag in Disney's 1991 Beauty and the Beast where a tiny character in a crowd steps "over" a sign that is above a door he's walking by. Easy to examine with a jog/shuttle dial on laserdisc; not so much on later formats.
