Try changing setting the HLS as M2TS in the behavior tab. It should make the video more fluid.

I'm on Windows 7 64-bit, Firefox 102.0 64-bit, licensed VDH 7.6.3a1 beta, CoApp1.6.3.

That's the sort of thing you should ALWAYS post when you are reporting a problem. It's
not that much. Anybody can do it.

I picked this video at random:

https://artgrid.io/clip/456211/bolivia-mother-son-walking

I downloaded the 3840x2160 variant that VDH offered. Then I did the usual thing to
download this with ffmpeg. I was expecting to find timed_ID3 data. What I found was a
master HLS manifest with 6 Programs. Each program consisted of a single stream of video
at various resolutions. There is no audio with this clip. To my surprise, there is no
timed_ID3 data, either.

I downloaded the 3840x2160 stream with ffmpeg (happened to be -map 0:5), then played the
2 downloaded files back to back several times. It took a few times but I finally did
notice the jerkiness. You have to just stare at the woman's feet as she walks. In the
ffmpeg copy, she seems to be walking smoothly. In the VDH copy, there's a tiny hitch in
her steps every so often. It's really hard to notice. I had to play the thing 4 or 5
times before I saw it.

This is pretty much the best possible example Michel could get to prove that VDH is doing
something to damage this video . . . and maybe others. We don't have any extraneous
distractions like timed_ID3 data, captions, or even an audio track. There is only the
video track. Nothing but video. VDH downloads it with jerks & jumps, ffmpeg downloads
it looking perfect.

There is an issue to investigate here.
