"NTSTC content at 23.976 I'd hope the player would just speed up at that point, but even if not... judder at 120 Hz is better than at 60 Hz."

I'd bet money when TVs are advertised at 120 FPS, they're really 119.88 FPS, so no judder showing 23.976 FPS and the other NTSC-off display rates.

Some content is truly exactly 24 FPS or 30 FPS though, so whichever path the TV goes (i.e. NTSC rate or integer rate) the same problem will exist. I suppose some TVs might have extremely fancy film mode detection which catches the occasional frame difference, but I doubt mine does :D
