I saved the movie to desktop. It wasn't protected.
23.98fps (NTSC video 24FPS)
Data Rate is 1267.91 kbps
Played smoothly for me as far as I can tell. I really don't like 24fps. I can see that motion issue. Not dropped or stutter frames though. There's also several shots which might be 60fps (or similar) slowed to 24fps. Some of those showed the kind of motion that bothers me (not smooth motion . . . maybe as if it needed frame blending).
That's a fairly high data rate and H.264 takes more computer power to decode than other codecs. That combined with the data may certainly create some issues on some computers.
