I just updated a vero to the kernel you are running. It wasn’t behaving at all until I did that. Could you try doing that and checking you get output like this:
osmc@vero4tv:~$ sudo apt-get install --reinstall vero364-image-4.9.113-63-osmc

OK, I’m stumped. I’ve tried playing those two clips from USB NTFS and through smb from an NTFS drive (via 1gb ethernet) and can’t reproduce anything I would call ‘stuttering’ (a stop-start behaviour with a frequency less than a second) or choppy.
You mean the kernel as I suggested or are you referring to an earlier update?
That’s useful - a lot more than ‘stuttering’, I’d say. Have you tried the alternative video_ucode.bins discussed above? Which are you on now?
Better to do it with the command line. I was writing instructions earlier but uploading your clips to our server so discourse was being unresponsive. Here it is again:
